What is the total resistance of the circuit? (Use ( V = IR ))

Explanation: An ammeter measures flow through a component. To measure how many electrons go through a bulb, you must break the wire and put the ammeter in the same path (series). Putting it in parallel creates a short circuit.

Explanation: Branch 2: V=9V, R=6Ω. I = 9/6 = 1.5A. f2 science electricity exercise top

Explanation: Total current = Sum of branch currents. ( I_{total} = 3A + 1.5A = 4.5A ).

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 What is the total resistance of the circuit

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.

If a voltmeter is placed across L1 and reads 1.2V, what is the voltage across L2? Putting it in parallel creates a short circuit

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.
