Q3. What is power , why use relay in electric current
Ans. 
Power is the rate at which energy is transferred. Relays are used to control high power circuits with low power signals.
• Power is measured in watts and is the product of voltage and current

• Relays are used to isolate high power circuits from low power control circuits

• Relays can also be used to switch multiple circuits with a single control signal

• Examples of relay applications include motor control, lighting control, and

Q2. What is relay and difference between relay nad fuse?
Ans. 
A relay is an electrically operated switch that opens or closes circuits. A fuse is a protective device that melts when current exceeds a certain level.
• Relays are used to control high voltage circuits with low voltage signals.

• Fuses are used to protect circuits from overloading and short circuits.

• Relays can be used to switch AC or DC circuits.

• Fuses are one-time use and need to be replaced after they melt.

• Relays have mov

Q1. How to calculate Boiler direct & indirect efficiency ?
Ans. 
Boiler efficiency can be calculated by measuring the heat input and heat output of the boiler.
• Calculate the heat input by measuring the fuel flow rate, fuel calorific value, and fuel consumption.

• Calculate the heat output by measuring the steam flow rate and steam enthalpy.

• Direct efficiency = (Heat output / Heat input) * 100%

• Indirect efficiency = Direct efficiency * Boiler efficiency of other components (like economizer
