Ch. 4 Circuits And Transformers Equations Flashcards
1
Q
Transformer law for voltage (direct relationship)
(VOLTAGE AND TURNS)
A
Vs/Vp = Ns/ Np
2
Q
Transformer law for current (inverse relationship) (CURRENT AND TURNS)
A
Is/Ip = Np/Ns
3
Q
Relations of voltage to current in a transformer (inverse relationship)
(CURRENT AND VOLTAGE)
A
Is/Ip = Vp/Vs
