220V 100W L 1.006H 220V 60HZ 3pF
a. Using Ohm’s Law, compute the voltage and current for each
component. Use the formula Z = Vt / It.
b. Compute and record the magnitude and phase angle of the impedance
using the equation Z= R + RL + jXL – JXC. Use 3uF for the value of C,
1.006H for the value of L and for the resistance is computed based on
the specification of the lamp.
c. Compute and record for the total power using the formula: Pcomputed = Scosθ
d. Compute and record the reactive power and apparent power using the
formula
Scomputed = V2/Z
Qcomputed = √S2 − P2
e. Compute for the reactive power (measure) and apparent power
(measured) using the formula.
Q = Ptanθ
S = P/ cos θ
f. Compute the percent difference between the measure and the computed
value of the impedance.
