Given :

Resistance of the electric kettle = 30 ohm

Voltage = 240 V

To find :

The value of current and the power rating of the electric kettle .

Solution :

Let the current be I and power be P .

Voltage = ( current ) * ( resistance )

now ,

240 V =  I * 30 ohm

=> I = ( 240 / 30 ) A

=> I = 8 A

Power = ( Voltage * Voltage ) / ( resistance )

=> P = ( 240 * 240 ) / 30 W

=> P = 1920 W

The value of current is 8 A and the power rating of the electric kettle is 240 V , 1920 W .
