Compare the power used in the `2 Omega` resistor in each of the following circuits :
(i) a `6V` battery in series with `1 Omega and 2 Omega` resistors, and
(ii) a `4 V` battery in parallel with `12 Omega and 2 Omega` resistors.

Explanation

To compare the power used in the 2-ohm resistor in the two given circuits, we will analyze each circuit step by step.

### Circuit (i): 6V Battery in Series with 1Ω and 2Ω Resistors

1. **Identify the Circuit Configuration**:
- We have a 6V battery connected in series with a 1Ω resistor and a 2Ω resistor.

2. **Calculate the Total Resistance**:
