Hazards of Series RLC CKTHazards of Series RLC CKT

Inductive reactance is close to capacitive reactance so they equal out Xc = XL

Left with only pure resistance to oppose the flow of current

Therefore Z=R

Series Resonant When Z is minimal and I is

maximum Resonant CKT

Causes an extremely high voltage in the ckt

R = .5Ω XL = 60ΩXc = 60Ω120 V , 60 Hz

The only opposition to current flow is the .5 ohm resistor

I=240A
