A transformer working on a 240 V AC supplies a voltage of 8 V to an electric bell in the circuit. The number of turns in the primary coil is 4800. Calculate the number of turns in the secondary coil.

Answer»

Vp = 240V

Vs = 8V 

Np = 4800

\(\cfrac{V_s}{V_p}\) = \(\cfrac{N_s}{N_p}\)

Ns\(\cfrac{V_s\times N_s}{240}\) = 160
