Question

What current is taken by a 3 kW electric geyser working on 240 V mains?

Answer 1

Answer:

$I = \ 0.0125 \times 10^{-3}  \ Ampere$

Explanation:

As per the question,

Given data:

Voltage supplied to geyser = 240 Volt

Power supplied = 3 kW

Since we know that the power supplied to geyser is equal to voltage supplied to geyser multiplied by the current flowing through it.

Therefore,

Supplied power = Voltage supplied × current

⇒ 3 kw = 240 volt × I

As we have

1 kW =1000 watt

Therefore,

3 kW = 0.003 Watt

So,

I = 0.003/240

I = $0.0125 \times 10^{-3}  \ Ampere$

Hence, the required current taken by electric geyser = $0.0125 \times 10^{-3}  \ Ampere$
