Aparallel circuit has a total current of 4 amperes and an equivalent resistance of .5 ohms. what is the power in this circuit?

=8.0 Watts

Explanation:

Power is a ratio of work done over time. The power in an electric circuit is calculated using the following formula:

P=I²R

P is power, I is  current, R is resistance

Therefore,  Power= 4²ₓ 0.5Ω

=8.0 Watts

The power in the parallel circuit is 8 W.

Explanation:

Power in an electric circuit is defined as the current generated for a given amount of input voltage. So power of an electric circuit is directly proportional to the product of current and voltage in the circuit. The mathematical representation is

As per Ohm’s law, the current flowing in a closed circuit is directly proportional to the voltage applied to the circuit and resistance is the constant of proportionality between them. So

Thus the formula for power in terms of resistance will look like

As it is given that the net current in the parallel circuit is 4 A and equivalent resistance of the parallel circuit is given as 0.5 ohms. Then power is

Thus, the power in the parallel circuit is 8 W.
