Answer:
12.99 Hz
Explanation:
Resonance is said to occur in an RLC circuit when maximum current is obtained from the circuit. Hence at resonance; XL=XC and Z=R.
XL= inductive reactance, XC= capacitive reactance, Z= impedance, R= resistance
The resonance frequency is given by;
fo= 1/2π√LC
L= 3×10^-3 H
C= 0.05 F
π= 3.142
Substituting values;
fo= 1/2×3.142√3×10^-3 × 0.05
fo= 12.99 Hz
Therefore the resonance frequency of the RLC circuit is 12.99 Hz
