If a domestic appliance draws 2.5 A from a 220-V, 60-Hz power supply find
Q the average of the square of the current

Explanation

To find the average of the square of the current for a domestic appliance drawing 2.5 A from a 220-V, 60-Hz power supply, we can follow these steps:

### Step 1: Understand the Concept of RMS Current
The RMS (Root Mean Square) current is a way to express the effective value of an alternating current (AC). For a sinusoidal AC current, the RMS value is given by the formula:
\[ I_{RMS} = \frac{I_{peak}}{\sqrt{2}} \]
However, in this case, we are directly given the RMS current, which is 2.5 A.
