A3. Answer: B (Series)
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. f2 science electricity exercise top
Volts (V)
): The electrical "push" or potential difference that moves the charge. Measured in using a voltmeter. Resistance ( This report synthesizes key findings from common Form

As you finish this review, memorize this "Don't Do" list: Draw a diagram of a simple series circuit
- Draw a diagram of a simple series circuit.
- What is the difference between a series and parallel circuit?
- A circuit consists of two resistors connected in parallel. If one resistor has a resistance of 2Ω and the other has a resistance of 4Ω, what is the total resistance of the circuit?
- Memorise symbols: cell, battery, resistor, bulb, switch, ammeter, voltmeter.
- Always label units in answers (V, A, Ω, W).
- Practice redrawing circuits to identify series/parallel sections.
- Use Ohm’s Law as your anchor – nearly every numerical returns to ( V = IR ).
Annotate Diagrams:
When given a circuit diagram, immediately write down the known V, I, and R values next to each component.
Formula:
F2 exercises frequently require calculating circuit values using Ohm's Law. V=I×Rcap V equals cap I cross cap R
Electricity is a fundamental chapter in Form 2 Science that bridges theoretical physics and real-world applications. Mastery requires both conceptual clarity and hands-on problem-solving. This essay outlines essential exercise types, step-by-step solutions, and common pitfalls, serving as a complete revision toolkit.
