Final answer:
To find the apparent power in the given circuit, calculate the total impedance of the parallel components and then use the formula S=V^2/Z, where S is the apparent power, V is the voltage, and Z is the impedance.
Step-by-step explanation:
To find the apparent power delivered to a circuit with an 8Ω inductive reactance in parallel with a 4Ω resistance by a 10V AC source, we first need to find the total impedance of the parallel circuit. We can use the formula for combined impedance in a parallel circuit, which is Z=1/((1/R)+(1/X_l)), where R is the resistance and X_l is the inductive reactance. Once the total impedance is calculated, the apparent power, S, is given by the formula S=V^2/Z, where V is the voltage of the AC source. Note that the apparent power is measured in volt-amperes (VA).
