Answer:
a.1127.7Ω
b.0.1714A
c.

Step-by-step explanation:
From our knowledge of AC Circuit, where we have the resistor arranges in series with the capacitor, the total impedance(Z) of the circuit is given as

Where R is the resistor value in the circuit and
is the circuit capacitance due to the capacitor in the circuit and is express as

By inserting values, we can determine the value of the capacitance

since the resistor value is 700Ω, we can substitute into the equation for the impedance

b. from the expression of Ohms law,

the voltage in this case is the amplitude of the voltage in the question i.e 120v
Hence

C. the phasor angle is express as
