Question

How much power is produced if a voltage of `2 V` is applied to a circuit with a resistance of `48 Omega`?

Answer 1

`2^2 //` 48 = 1`//`12 watt

Explanation:

For a resistive circuit the dissipated Power P is
P = `IV` = `I^2` R = `V^2` / R

In the question the word produced is misleading. There is no generation of power in the stated circuit.
