Current and Turns Ratio

<^< Examples: Voltage and Turns Ratio | Course Index | Examples: Current and Turns Ratio >^>(:nl:)

If a transformer is loss-free (i.e. no power is lost in the core or in the windings), the primary and secondary powers (P'_P_' and P'_S_', respectively) will be identical.

>>center<<Hence: P'_P_' = P'_S_'

thus: V'_P_' x I'_P_' = V'_S_' x I'_S_'

Hence: V'_P_'/V'_S_' = I'_S_'/I'_P_' and I'_S_'/I'_P_' = N'_P_'/N'_S_' >><<(:nl:)(:table style="clear:both":)
