in a circuit with a constant voltage of the battery, more resistors with the same values are added in parallel. what is the change in the power dissipated from the circuit?
The change in the power dissipated from the circuit when more resistors with the same values are added in parallel depends on the total resistance of the circuit.
When resistors are connected in parallel, the total resistance decreases. This is because the total resistance in a parallel circuit is given by the reciprocal of the sum of the reciprocals of the individual resistances.
So, when more resistors with the same values are added in parallel, the total resistance decreases, which in turn increases the total current flowing through the circuit.
According to Ohm’s Law, the power dissipated in a resistor is given by P = I^2 * R, where P is the power, I is the current, and R is the resistance.
Since the current increases when more resistors are added in parallel, the power dissipated in each resistor also increases.
Therefore, the change in the power dissipated from the circuit is an increase when more resistors with the same values are added in parallel.
