Question

electric iron of 1 kilowatt is operated at 220 volt find which of the future that respectively rated at 1 ampere 3 ampere and 5 ampere can we use in it​

Answer 1

Answer:

For us to get the fuse that is suitable, we must get the total current flowing through the circuit.

The formulae to get this is :

Power(watts) =Voltage(volts) ×current(amps)

In this case power=1000watts, votage=220v

Current =1000/220=4.55A

The suitable fuse is 5A since it is slightly above the current flowing through the circuit.

Explanation:

Answer 2

Answer:

Find which of the following fuses that respectively rated ay ... Power(watts ) =Voltage(volts) ×current(amps) ... the fuse that can be used for operating the electric ...
