Calculate the output voltage in a transformer if input voltage is 240V and ratio of the number of turns in secondary to the primary coil is 3:2. Can you please write the full solved answer. |

Answer» Input voltage = 240VRatio of the NUMBER of TURNS in secondary to the primary coil = 3 : 2TO Find :Output voltage.Solution :❖ The voltage and currents in a transformer are related as» For a step-up transformer, k > 1 and for a step-down transformer, k < 1Given that, By substituting the given values;Knowledge BoosteR :A transformer is essentially an a.c. device. It can't work on d.c. It changes alternating voltages/currents. It doesn't affect the frequency of a.c.The small transformers are self-cooled, which transfer heat directly to the surrounding. Large transformers are cooled by placing them in oil tanks to prevent overheating. |
