a) What is the resistance of a conductor? Mention the factors on which the resistance of a conductor depend.
b) b) An electric bulb of `200 Omega ` draws a current of 1 ampere. Calculate the power of the bulb the potential difference at its ends and the energy in KWh consumed burning it for 5h.

Explanation

Power of the bulb
Power of the bulb `P = PR = (1)^(2)x 200`
P = 200W
Energy consumed by bulb in 5h in burning
= Power x time
= 200 x 5
= 1000wh = 1 kwh.
