Find the rms value of current if the peak value of an alternating voltage applied to a 20 `omega` resistance is 8 V . Also write the equation for instantaneous current if the voltange frequency is 60 Hz.

Explanation

To solve the problem step by step, we will find the RMS value of the current and then write the equation for the instantaneous current.

### Step 1: Identify the given values
- Peak voltage (E₀) = 8 V
- Resistance (R) = 20 Ω
- Frequency (f) = 60 Hz

### Step 2: Calculate the peak current (I₀)
