Question

If R= 2 ohm the potential difference across 2R resistance will be?

Answer 1

If R= 2 ohm, the potential difference across 2R resistance will be **4 volts**.

This can be calculated using the following equation:

```

V = IR

```

where:

* V is the voltage

* I is the current

* R is the resistance

If we assume that the current flowing through the 2R resistor is 2 amps, then the potential difference across the resistor will be:

```

V = 2 amps * 2 ohms = 4 volts

```

Therefore, the correct answer is **4 volts**.

Answer 2

If R is 2 ohms, the potential difference across a 2R resistance (where R = 2 ohms) will be 4 volts.
