A alternating voltage given by `V = 140 sin 314 t` is connected across a pure resistor of 50 ohm. Find the rms current through the resistor.

Explanation

To find the RMS current through a pure resistor connected to an alternating voltage, we can follow these steps:

### Step 1: Identify the given values
The alternating voltage is given by the equation:
\[ V(t) = 140 \sin(314t) \]
From this equation, we can identify:
- The peak voltage \( V_0 = 140 \, \text{V} \)
- The angular frequency \( \omega = 314 \, \text{rad/s} \)
