Q.1 What does 10V AC mean? Is it the RMS voltage or Peak voltage or Average voltage?
For example 230V AC supply means, 230Vrms AC Supply.
Q.2 What does the Voltmeter in AC mode show? Is it RMS value or peak value?
Q.3 Can fuses with an AC voltage rating be used in a DC applications?
Q.4 Why in a three pin plug the earth pin is thicker and longer than the other pins?
Q.5 Why humming sound occurred in HT transmission line?
Q.6 What the main difference between UPS & inverter?
Answer: Uninterrupted power supply is mainly use for short time. Means according to ups VA it gives backup. Ups is also two types: on line and offline. Online ups having high volt and amp for long time backup with high dc voltage. But ups start with 12v dc with 7 amps. but inverter is start with 12v,24,dc to 36v dc and 120amp to 180amp battery with long time backup
Q.7 Why the capacitors work on ac only?
Answer: Generally capacitor gives infinite resistance to dc components (i.e., block the dc components). It allows the ac components to pass through.
Q.8 Why We use of Stones/Gravel in electrical Switch Yard
Answer: Reducing Step and Touch potentials during Short Circuit Faults Eliminates the growth of weeds and small plants in the yard Improves yard working condition Protects from fire which cause due to oil spillage from transformer and also protects from wild habitat.
