Current electricity written questions
Structured and data-based Paper 2 practice for current electricity: current, charge, e.m.f., potential difference, resistance, and I–V characteristic graphs.
Learning goals
- State current as rate of charge flow measured in amperes
- Distinguish conventional current from electron flow
- Apply charge equals current multiplied by time
- Define source e.m.f. as work done per unit charge around a circuit
- Calculate total e.m.f. for sources in series
- Define component potential difference as work done per unit charge
- State resistance as potential difference divided by current
- Apply resistance equals potential difference divided by current
- Apply wire-resistance proportionalities for length and cross-sectional area
- Describe the effect of temperature on metallic resistance
- Sketch and interpret required current–voltage characteristics
