If a domestic appliance draws 2.5 A from a 220-V, 60-Hz power supply find
Q(d) the supply voltage amplitude

Explanation

To solve the problem of finding the supply voltage amplitude (Vm) from the given RMS voltage (Vrms), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Relationship Between RMS and Amplitude**:
The relationship between the RMS voltage (Vrms) and the peak voltage (Vm) is given by the formula:
\[
V_{rms} = \frac{V_m}{\sqrt{2}}
