Question

When an ac power is applied to a reactive load then the voltage is ans?

Answer 1

Answer:

First, we use Ohm's law ( V = I × R ), to find the current through the resistor. The voltage across the resistor is V = 9 V. The resistance of the resistor is R = 100 ?. Then, we can use the power rule ( P = I × V ), to find the power dissipated by the resistor

Answer 2

An ac power is assigned to a reactive load then the voltage is 90 degrees out of phase with the presence of current.

• Power consumed by a solely reactive load is zero. So, the ac power in the circuit is zero.
• Real power is P = VI cos ϕ
• Here ϕ is representing the angle between voltage and current.
• As the ac power is zero, the power component will be zero.
• It occurs when ϕ = 90° i.e. the voltage is 90 degrees out of phase with the presence of current.

Hence, when ac power is correlated to a circuit possessing a reactive load, the voltage is 90 degrees out of phase with the current.
