Question

An electrical appliance is rated as 60 W - 100 V. Calculate the magnitude of current will flow through the appliance when in use.​

Answer 1

Explanation:

60W−150V power rating of appliance means, "if appliance is put on a circuit of 150 volt, it will consume 60W electrical power i.e. electric energy consumed by it in 1 sec is 60 J.

(b) P=VI

∴ Current will through the appliance

I= VP

= 150V/60W

=0.4A

Answer 2

Answer:

An electrical appliance is rated as 60 W - 150 V." means it consumes power of 60 W at 150 V. Hence, current flowing through appliance when in use is 0.4 A

Explanation:

60W−150V power rating of appliance means, "if appliance is put on a circuit of 150 volt, it will consume 60W electrical power i.e. electric energy consumed by it in 1 sec is 60 J.

(b) P=VI

∴ Current will through the appliance

$I= \frac{P}{V}$
