Question
Download Solution PDFA 120 Ω resistor is in parallel with a capacitor with a capacitive reactance of 40Ω. Both components are across a 20 V AC source. What is the magnitude of the total current through the circuit?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is option 4):
Concept:
The magnitude of the total current through the circuit
I =
where
IR is the resistive component of current
IL is the Inductive component of current
IC is the Capacitive component of current
IR =
V is the voltage
R is the resistance
IC =
Xc is the capacitive reactance
IL =
XL is the inductive reactance
Calculation:
The impedance of a network is given as
I =
IR =
=
Ic =
=
I =
=
=
=
