How many turns are in the secondary winding

Reference no: EM13254744

a) The primary winding of a transformer has 1200 turns, and is connected to 120 V A.C. (r.m.s. value). The secondary has a 25 W load resistor, carrying 30 mA current (r.m.s. value). What is the average power input (in watts) at the primary winding?

b) Continuing, what is the r.m.s. value of the current (in amps) in the primary winding?

c) Continuing, how many turns are in the secondary winding?
