Q1. 1kva how many amps required
Ans. 
The number of amps required for 1kVA depends on the voltage.
• The formula to calculate amps is: Amps = kVA / Voltage

• For example, if the voltage is 120V, then the amps required for 1kVA would be 8.33A

• If the voltage is 240V, then the amps required for 1kVA would be 4.17A
