Calculate the total impedance for a circuit having the following value...
If we only have the value of resistance (R), we cannot calculate the total impedance (Z) for a circuit.
The total impedance in a circuit is calculated by considering the resistance (R) and the reactance (X). The reactance is the opposition to the flow of alternating current caused by inductance (L) or capacitance (C) in the circuit.
To calculate the total impedance, we need to know the values of both resistance and reactance.

Calculate the total impedance for a circuit having the following value...
Concept:
In a series RLC circuit, the impedance is given by
R is resistance
XL is inductive reactance = ωL
XC is capacitive reactance = -1/ωC
(XL – XC) is net reactance
At the resonant frequency, inductive reactance is equal to capacitive reactance i.e. XL = XC
So, at this condition the impedance is minimum, and it is equivalent to R.
Explanation:
Given that, resistance (R) = 5 Ω
Capacitive reactance (XC) = 20 Ω
Inductive reactance (XL) = 12 Ω
Net Impedance Z is calculated as:
