To make a battery of two cells, the negative terminal of one cell is connected to the negative terminal of the other cell.
Electrical Cell
The main power supply of an electrical circuit is the electric cell.
It contains two electrodes at its two terminals.
The cathode is present in the positive terminal and the anode is present in the negative terminal.
It generates electricity by converting chemical energy into electrical energy.
Therefore, a potential difference is created between the two terminals.
This sets the positive charges to flow from the positive terminal to the negative terminal.
Hence, due to this continuous flow of charge, a current is generated inside the circuit.
Polarity of Electric Cell
It contains two terminals: positive and negative.
In reality, electrons or negative charges flow from the negative terminal to the position terminal.
The flow of current is taken opposite to the flow of charge in the positive direction due to general convention.
Hence, to maintain this continuity of flow of the current, the negative terminal of one cell must be connected to the positive terminal of the other cell.

When the balance point is obtained in the potentiometer, a current is drawn from
and are three identical bulbs connected as shown in Figure 12.8. When all the three bulbs glow, a current of 3A is recorded by the ammeter A.
How much power is dissipated in the circuit when all the three bulbs glow together?
