Показать описание
9702/13/M/J/21: In the circuit shown, a potentiometer of total resistance 120 Ω is connected in parallel with a resistor of resistance 150 Ω and a resistor of resistance R. The battery has electromotive force (e.m.f.) 12 V and negligible internal resistance. The voltmeter reads 0 V when the slider of the potentiometer is 1/4 of the way from its lower end, as shown. What is resistance R ? #9702s21p13 #AScircuitsP1 #ASpotentiometerP1 #ASpotentialDividerP1 #Lv2
