Question

53.
Write a formula for calculating the amount of heat(H) produced in a resistor
of resistance R when current is passed through it for timet.​

Answer 1

Answer:

Here is your answer-

Consider a resistor of Resistance R. Let the current flowing through the resistor be I and potential difference across its ends be V.

In time t, let Q amount of charge flows through the resistor.

Work done on Moving charge will be,

W =V x Q ---------(1).

According to the definition of electric current,

Q = I x t -----------(2).

Putting equation (2) in (1),

W = V x I x t.

And the work done is dissipated as heat.

Therefore,

Heat produced, H=W=V x I x t => VIt.

H= VIt.

According to Ohm's law V= IR.

Putting this in equation(2), we get,

H= IR x It.

Therefore, Heat= I2(square)Rt.

I square x R x t.
