Sample questions
A battery of electromotive force (e.m.f.) $ \varepsilon $ and internal resistance r is connected to five identical wire wound resistors in a circuit. Each resistor between points P and Q has a resistance of $ 300\Omega $. Two of the resistors are labelled X and Y as shown. The ta…
A switch, resistor of resistance R and a component Z are connected to a battery of electromotive force (e.m.f.) E and internal resistance r. An ammeter and voltmeter are also connected to the circuit as shown in Fig. 6.1. Fig. 6.1 Fig. 6.2 shows the current I and potential differ…
The circuit diagram shows a battery of e.m.f. $ E $ and internal resistance $ r $ connected to a variable resistor $ R $. Fig. 5.1 The current I in the variable resistor is measured using an ammeter and the potential difference V across the variable resistor is measured using a v…
