Transformers The transformer equation:
N1 V1 = N 2 V1 Where: • N1 = Number of turns on coil 1 • N2 = Number of turns on coil 2 • V1 = Voltage on coil 1 • V2 = Voltage on coil 2
1. A transformer has 100 turns on coil 1 and 200 turns on coil 2. a. What will the voltage on coil 2 be if the voltage on coil 1 is i. 10 volts? ii. 200 volts? iii. 1000 volts? b. Is this a step up or step down transformer? c. Would you expect to find a transformer like this connecting a power station or home to the national grid? 2. A transformer has 1000 turns on coil 1 and 600 turns on coil 2. a. What will the voltage on coil 2 be if the voltage on coil 1 is i. 240 volts? ii. 10 volts? b. Is this a step up or step down transformer? c. Would you expect to find a transformer like this connecting a power station or home to the national grid?
