F2 Science Electricity Exercise Top -

If you are a Form 2 (F2) student, you have likely reached the turning point of your science syllabus: Electricity . It is a leap from Biology and Chemistry because you cannot see electrons. You can only see their effects—light, heat, and movement.

Calculate the current flowing through Branch 1. (( I = V/R )) Q8. Calculate the current flowing through Branch 2. Q9. Calculate the total current drawn from the battery. Q10. Top Question: If you add a third bulb in parallel to the first two, what happens to the brightness of the original two bulbs? Explain why. Answer Key & Detailed Explanations Do not just check the answer; read the why . f2 science electricity exercise top

Three identical bulbs are connected in parallel to a 6V battery. What is the voltage across each bulb? A) 2V B) 3V C) 6V D) 18V If you are a Form 2 (F2) student,

Explanation: The "top rule" for parallel circuits: Voltage is the same across every branch. The battery pushes 6V, so every component gets the full 6V. Calculate the current flowing through Branch 1

Draw the circuit diagram for the description above. (Answer key: Draw a rectangle. Cell on the left, ammeter on top, L1 on right, L2 on bottom, all in one closed loop). Section C: Parallel Circuit Challenge (Top Difficulty) Circuit: A 9V battery connected to two parallel branches. Branch 1 has a single 3Ω resistor. Branch 2 has a single 6Ω resistor.

An ammeter must always be connected in: A) Parallel to the component B) Series with the component C) Across the battery D) Reverse direction Section B: Diagram Analysis (Drawing & Calculation) Refer to the described circuit: Two bulbs (L1, L2) in series with a 3V cell. An ammeter reads 0.5A.
