The primary coil of a transformer has 200 turns and its secondary coil has 22,000 turns . It is connected to a 220 V AC source at the input and a resistance of 110 `kOmega1 is connected across the output . What is the output potential difference per turn and power delivered to the load ?

Text Solution

AI Generated Solution

To solve the problem step by step, we will first calculate the output potential difference per turn and then the power delivered to the load. ### Step 1: Calculate the Output Voltage (V2) We know the relationship between the primary and secondary voltages and the number of turns in a transformer: \[ \frac{V_1}{V_2} = \frac{N_1}{N_2} ...
