Draw a circuit diagram of an electric circuit containing a cell, a key, an ammeter, a resistance of `2 Omega` in series with a combination of two resistors (`4 Omega` each) in parallel and a voltmeter across the parallel combination. Will the potential difference across the `2 Omega` resistor be the same as that across the parallel combination of `4 Omega` resistors ? Give reason.

Explanation

### Step-by-Step Solution

1. **Draw the Circuit Diagram:**
- Begin by drawing a cell (battery) with positive and negative terminals.
- Connect a key (switch) in series with the cell.
- Next, connect an ammeter in series with the key.
- After the ammeter, connect a resistor of `2 Ω` in series.
- Then, create a parallel combination of two resistors, each of `4 Ω`. Connect these resistors in parallel after the `2 Ω` resistor.
