Thomson coefficient of a conductor is 10μVK. The two ends of it are kept at 50⁰C and 60⁰ C respectively. Amount of heat absorbed by the conductor when a charge of 10 C flows through it, is:

When a high resistance R is connected in series with a voltmeter of resistance G, the range of the voltmeter increases 5 times. Then G:R will be

A steady current is set up in a metallic wire of non-uniform cross-section. Then the drift velocity related the area of cross-section (A) as

Thomson coefficient of a conductor is 10μV/K.The two ends of it are kept at 50⁰C and 60⁰C respectively.Amount of heat absorbed by the conductor when a charge of 10C flows through it is

A 25 watt,220 volt bulb and a 100 watt,220 volt bulb are connected in series across 440 volt line
