Paper 1 · November 2002 · Current Electricity

In the circuit shown below the internal resistance of the cell is 0.2Ω. The electromotive force of the cell is 6V. What is the voltmeter reading when the current flowing through the cell is 2A?

A5.4 V

B5.6 V

C5.8 V

D6.0 V

Explanation

Terminal voltage V = EMF - I×r = 6 - 2×0.2 = 6 - 0.4 = 5.6V. Answer B.

A 2.0m long uniform rod of mass 1.0kg is pivoted at point P and it is in equilibrium under the forces acting on it as shown in the diagram (a force F at 60 degrees to the rod acting 50cm from the left end, the pivot P just right of that, and a 20N weight hanging from the right end). What is the value of force F?
The diagram shows two resistors of resistance 5000Ω and 2500Ω connected in series. A potential difference of 120V is maintained across them. The potential difference across the 5000Ω resistor is measured using a voltmeter of internal resistance 5000Ω. What is the reading of the voltmeter?
The diagram shows a uniform resistance wire MN of length 100.0cm which is connected to a standard cell of e.m.f. 1.5V and of negligible internal resistance.
