This is a question on circuit connection.
1) Cells in series
The effective voltage is the sum of the voltage of individual cells.
V(effective) = V1 + V2 + V3 + .......
Effective current is equal through out the circuit.
I ( effective) = I1 = I2....
2) Cells in parallel
The effective voltage is same across the circuit.
V (effective ) = V1 = V2...
I ( effective) = I1 + I2 + .......
The effective current is the sum of individual currents of each cell.
Answer:
The first series connection :
we have : 1.2 + 1.2 + 1.2 + 1.2 = 4.8 V
The second connection is in parallel hence voltage is same across the circuit.
The answer is therefore 4.8 V
