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__.
decrease
Electric Power is the rate at which energy is dissipated or consumed in an electric circuit. P=VI=V2R
Power is inversely proportional to resistance. In a series combination, total resistance increases, hence the power decreases.
In series combination of electrical appliances, total electrical power decreases.
