For the circuit element of Problem 2.3, calculate (a) the instantaneous power absorbed, (b) the real power

Question:

For the circuit element of Problem 2.3, calculate

(a) the instantaneous power absorbed,

(b) the real power (state whether it is delivered or absorbed),

(c) the reactive power (state whether delivered or absorbed),

(d) the power factor (state whether lagging or leading).

Data From Problem 2.3:-

The instantaneous voltage across a circuit element is \(v(t)=359.3 \sin \left(\omega t+15^{\circ}\right)\) volts, and the instantaneous current entering the positive terminal of the circuit element is \(i(t)=100 \cos \left(\omega t+5^{\circ}\right)\) A. For both the current and voltage, determine

(a) the maximum value,

(b) the rms value,

(c) the phasor expression, using \(\cos (\omega t)\) as the reference.
