Question

Calculate the electrical energy consumed by the kettle if the boiling water for 12 minutes with 12.5A

Answer 1

Given that,

Current = 12.5 A

Time t = 12 min

Suppose the voltage of kettle is 250 V.

We need to calculate the power consumed

Using formula of power

$P=IV$

Where, I = current

V = voltage

Put the value into the formula

$P=12.5\times250$

$P=3.125\ kW$

We need to calculate the energy consumed

Using formula of energy

$E=P\times t$

Put the value into the formula

$E=3.125\times12\times60$

$E=2250\ KJ$

Hence, The electrical energy consumed by the kettle is 2250 KJ.
