Atransformer on a 220 v line has 55 loops on the primary and 440 loops on the secondary and draws a 4.00 a current. assuming no losses: (a) what is the voltage from the secondary? (b) what is the currency from the secondary? (c) what is the power output?

For transfomers (robots in disguise), there are equations to help us solve these problems.

Here are the equations you need:



is our V primary, is our V secondary, is our number of loops on our primary and is number of loops in our secondary.

Plugging our known values in, we can solve for the secondary voltage.




For current, we have another equation:



Just like before, we can plug in our known values:




Since we are told there are no losses, the input power must equal output power.

(0.5A)(1760V)=(220V)(4A) = 880W
