Yes you are not applying loop rule properly
Potential difference, also known as voltage, is the measure of electrical potential energy between two points in a circuit. In a multi cell circuit, potential difference refers to the difference in voltage between the positive and negative terminals of each cell.
Potential difference can be calculated by multiplying the current (in amps) by the resistance (in ohms) in the circuit. In a multi cell circuit, the potential difference is the sum of the individual potential differences in each cell.
The potential difference in a multi cell circuit can be affected by the number of cells connected in series, the individual voltage of each cell, and the resistance in the circuit.
Having multiple cells in a circuit allows for a higher potential difference to be achieved, which can be useful for powering devices that require a higher voltage. Additionally, multiple cells can provide a backup power source in case one cell fails.
In a multi cell circuit with varying resistance, the potential difference will remain constant if the cells are connected in series. However, if the cells are connected in parallel, the potential difference will decrease as the resistance increases due to the voltage being divided among the different branches of the circuit.
