Question

i. A wire of resistance 3.00 is stretched to twice its original length. The resistance o
new wire will be
(a) 1.5 D (b) 3.0 (c) 6.0 (d) 12
ii. A wire of resistance 4 is bent into a circle. The resistance between the ends of a
diameter of the circle is
(a) 4 (b) 1 (0)1/4 (d) 1/16
iii. Which of the following statement is correct?
(a) Electrons drifting in a conductor under the influence of an electric field are
accelerated by the field.
(b) The drift speed of the electrons in a conductor is of the order of a few mms-1
(c) All free electrons ina metal drift from a lower to a higher potential.
(d) Since the drift speed of electrons in metal is very small and the charge on an
electron is extremely small, only a small amount of current can flow in metals.​
