1.

Explain why electric lights in a building are connected in parallel rather than in series.

• When the bulbs are connected in parallel, the current through each bulb will be higher and hence each bulb will glow more brightly.

• Parallel arrangement also allows the bulbs to work independently. That is, when one bulb is fused or blown, the other bulbs can still work.

2.

Resistor A and B are in parallel. Would the addition of an extra resistor parallel to A and B increase or decrease the current flowing through the battery? Explain your answer.

• Adding a resistor in parallel decreases the effective resistance of a circuit.

• Using I=V/R, the current through the battery will increases.

### What our Physics Students and Parents say

“Concept First probably has the best Physics tutors in Singapore.”

— Adelle Wang, River Valley High School

CF probably has the best Physics tutors in Singapore. They are able to explain difficult concepts clearly, as they provide short cuts and teach much easier methods of comprehending theory. Tuition is usually seen as a tedious and tiring activity but I always feel like their lessons pass very quickly as it is well-paced, suited to his students needs, and interesting at the same time. My Physics grades have improved from an S during mid-years to a B during prelims under their tutorship.

“One thing I really appreciate about my tutors at CF is the fact that they cared for us all as individuals.”

— Liew Yee Kay, Anglican High School

I always had much difficulty with Physics and found it a cumbersome and boring subject. But after attending Concept First Physics tuition class, I slowly understood it and finally got an A1 at the end! One thing I really appreciate about my tutors at CF is the fact that they cared for us all as individuals. When I was unsure about other subjects like A. Math, my tutors would stay back after class with me to clear my doubts. And for that, I’m really thankful!

I attended Concept first at the start of 2023, initially I wasn't able to do well for physics and always attain a boarder line pass. However, after attending the lesson, I have improve a lot under Mr Kong teaching. Thank you Concept First and Mr Kong.

This school help brought my daughter's confidence back into physics. Seeing her coming back to herself compared to when in lower secondary really made the day. The school is also attentive and provides feedback. They even gave the students a treat during their last lesson with the school. Good job guys!

i've been with cf for less than a year, and i've gone from hating physics to being able to appreciate it a lot more. The teachers are very friendly and approachable, the materials given are extremely helpful and concise, the lessons are engaging and the teachers provide structured ways to answer questions. They ensure that you understand the content fully and don't mind any kind of questions 😀

Concept First Physics is an extraordinary tuition center that has truly transformed my son's understanding of physics. The dedicated tutors, with their immense knowledge and passion, provide exceptional personalized guidance. The small class sizes foster a supportive and engaging environment where my son feels confident to ask questions and explore challenging concepts. The center's innovative teaching methods and real-world applications make learning physics exciting and relevant. I am immensely grateful for Concept First Physics' commitment to nurturing my son's potential, and I wholeheartedly recommend them to any parent seeking outstanding physics tuition. I appreciate your efforts. Thank you.

The teachers in CF were very kind and willing to help even at unusual times. Helped me alot to love physics and constantly encouraged me to get better. The physics practical lessons are also very well organized by calvin and provide a safe evironment for student to practice for their practicals. Would recommend to anyone wanting to improve their physics

I scored consistently C6 for my physics and was about to drop the subject. After joining cf, I was able to understand the concepts better. Mr Seah uses a lot of acronyms to help students memorise keywords and definitions better. He also answers all my questions and takes the time to explain till I understand. Managed to get a A2 for my O levels.

I am very grateful that I studied in Concept First, the notes given were detailed and it was helpful to me in my revision. I did not expect learning physics to be fun but my physics tutor( Mr Seah) made it possible ☺️ He makes lessons super fun and makes physics much easier to understand for me. He gives great feedback in my work and encourages me a lot and I have managed to jump a few grades! Their 2-page summary notes are awesome too! Overall, I would really recommend Concept First, definitely worth it ! 😊

My journey with Concept First is one that was very fulfilling. The in-depth lessons equipped with questions of varying difficulty levels has allowed my to go from a C6 to A2 for physics in O-levels. I found their 2 page summaries extremely useful as revision. There was endless practice which allowed me to retain my knowledge. I also appreciate Mr Kong’s teaching which allowed me to grasp key concepts quickly and effectively and was apply to apply these concepts along with answering techniques

Mr Ram has been a fantastic teacher with good knowledge about the syllabus and the marking system of Cambridge. He is able to provide advice based on his experience as a student and as a teacher to ensure that our learning experience is optimized. He is also a friendly and casual teacher which bonds well with students and makes the learning environment less tensed. He is also readily available to answer our doubts and questions throughout the day even if it is late at night. He frequently asks questions on our learning experience to try and improve his method of teaching to cater to our different styles of learning. Overall, Mr Ram has been an exceptional teacher which helped me to improve in physics and brings out the best in his students.

Concept First tutors explain their concepts very clearly and provide ample exercises for the students to practise those new concepts. Having studied here for a year, they have greatly aided me in helping myself achieve a B in A Levels (initially U grader) as well as spark my passion for Physics (i once hated this subject). Though some may argue, coming from a higher ranking school, CF provides notes which are more helpful than school notes (we can agree to disagree). Definitely worth the cost.

CF has helped me to understand the concepts better as they offer a lot of practices and gives concise notes to help me in my revision. Before I attended lessons, I struggled to understand some topics but now I am confident in my physics knowledge and can clarify my friends' doubts. The teachers are really kind and funny. They will make lessons fun and engaging. I had always looked forward to attending lesson. ❤

Mr Kong has been nothing short of an excellent teacher whose dedication and commitment to his students cannot be understated. The materials that Concept First has provided is also detailed and helpful to examination revision. I would not hesitate to recommend Concept First to anyone and would like to commend the centre of a job well done.

concept first physics helped me to better understand physics overall and let me better grasp the concepts needed to understand the topic better. Together with the extremely useful notes, the 1 page summary guides and extensive help from Mr Kong i am able to revise adequately for my exams. Thank you!
