AC Flashcards
1
Q
DC circuit
A
circuit where the direction of the current / polarity of voltage is constant
2
Q
AC circuit
A
circuit where the direction of its current or polarity of voltage varies periodically with time
3
Q
peak value (for alternating current)
A
maximum value of I or V in either direction of zero value in periodic cycle
4
Q
r.m.s value of AC/V
A
value of AC/V that is equal to the steady DC/V which would dissipate heat at the same average rate in a given resistor
