Question 1 (a) A silver wire of 1.0 mm radius transfers 100 C charges within 1 hour. Silver has 5.8 x 102% electrons per m'. Find, (i) the current conducted in this wire. (ii) the drift velocity of the free electrons in the wire. (b) Estimate the resistivity of 3.5 m long wire with diameter of 1.2 mm has a resistance of 0.03 22. (2 marks) (3 marks) (3 marks) (c) A voltmeter shows 13.0 V when it is connected across the terminals of a battery. The voltmeter reading then drops to 12.0 V when the battery delivers a current of 3.0 A to a lamp. Find the internal resistance of the battery. (2 marks)
