When number of identical cells, in parallel combination are increased, the voltage of the circuit will
Decrease
Remain same
Depends on the internal resistance of the battery
Increase
The voltage of the circuit will remain same when numbers of cells in parallel are increased.
Two identical cells, each of emf 2 V and of unknown internal resistance r are connected in parallel. This combination is connected to a 4 ohm resistor. If the terminal voltage across the cells in the closed circuit is 1.5 V then the internal resistance of the cell is
In a series combination of electrical appliances, connected to a constant voltage power supply, if we add one more appliance with resistance R in series, then the total electrical power consumed in the circuit will__.
