Answer 1

Answer:

Explanation:

Given :

To derive an expression for the heat produced due to current "I" flowing through for  time "t" through a resistor "R" having potential Difference "V" across its end.

Solution :

We know that,

Voltage (potential diference across the ends of the conductor) = Current × Resistance (Resistance across the conductor)

$V = IR$

Power dissipated = Voltage × Current

⇒$P = VI = (IR)I = I^2 R$

Heat dissipated = Power × time

⇒ $H = P \times t = VI t = (IR)It = I^2 Rt$
