Write an expression for the electrical power spent in flow of current through a conductor in terms of
resistance and potential difference

Explanation

To derive the expression for electrical power spent in the flow of current through a conductor in terms of resistance and potential difference, we can follow these steps:

### Step 1: Understand the relationship between power, energy, and time
We know that power (P) is defined as the rate at which energy (E) is used or dissipated over time (t). The formula for this relationship is:
\[ E = P \times t \]
This means that energy is equal to power multiplied by time.
