Question

When 6v is applied across the ends of a resistor for 2seconds ,24 J of energy produces,then what will be the current through it?​

Answer 1

Given:

6V is applied across the ends of a resistor for 2seconds and 24 J of energy is produced.

To find:

Current through circuit?

Calculation:

First of all, let's find the power :

• Power (P) =Energy/Time = 24/2 = 12 watt.

Now, the general expression for power in a circuit is :

$\therefore P = V \times I$

$\implies 12 = 6\times I$

$\implies I = \dfrac{12}{6}$

$\implies I = 2 \: ampere$

So, current through circuit is 2 amperes.
