Question

& Answer the following
34. (a) state Jaules law of heating .write the
mathematical form of this law

​

Answer 1

Answer:

A quantitative form of Joule's law is that the heat evolved per second, or the electric power loss, P, equals the current I squared times the resistance R, or P = I2R. The power P has units of watts, or joules per second, when the current is expressed in amperes and the resistance in ohms

H square is equal to I square into R into T. This is called joule's law of heating. The devices which works on this principle are Electric Heater, Immersion water Heater, Electric bulb,Fuse wire etc.

Answer 2

Answer:

heat produced in a resistor is directly proportional to the square of current for a given resistance , resistance for a given current, time for which the current flows through the resistor

H=I2RT( I SQUARE R T)
