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…
Which of the following is not a source of electromotive force (e.m.f.)? A chemical cell B light-dependent resistor C power supply D solar cell
Two filament lamps X and Y are connected in parallel to a supply. The power dissipated by lamp X is 24 W and the power dissipated by lamp Y is 6.0 W. The supply has electromotive force (e.m.f.) 12 V and negligible internal resistance. What is the total current drawn from the supp…
