• resistor

• inductor

in a series RLC circuit what determines if voltage is leading or lagging

• Xl-Xc

• R-Xl

• Xc-Xl

• R-Xc

what method do we use to find total voltage in an RLC

• tip to tail

• phasor sum

• addition

• maths

if a circuit is operating at resonance what is opposing current

• resistance

• capacitive reactance

• reactance

• inductive reactance
