In a transformer without any loss in power, there are 5000 turns in the primary and 250 turns in the secondary. The primary voltage is 120 V and the primary current is 0.1 A. Find the voltage and current in the secondary. |

Answer» NP = 5000 NS = 250 VP = 120 IP = 0.1A \(\cfrac{V_s}{V_p} = \cfrac{N_s}{N_p}\) \(V_s\) = \(\cfrac{V_s}{V_p} \times V_p\) = \(\cfrac{250}{5000}\times 120 =6V\) \(\cfrac{V_s}{V_p} = \cfrac{I_p}{I_s}\) \(I_s = \cfrac{I_p}{V_s}\times V_p=\cfrac{0.1}{6}\times 120 =2A\) |
