Question

Electric meter of your house is rated as (250 V- 20 A).
What is the maximum load (in kW) that you can connect
with this meter ?
​

Answer 1

Answer:

5kW

Explanation:

P= V×I

= 250×20

=5000 watt

= 5kW

Answer 2

Given,

The electric meter of your house is rated as (250 V- 20 A).

To Find,

What is the maximum load (in kW) that you can connect with this meter?

Solution,

We can solve the question as follows:
It is given that the electric meter of your house is rated as (250 V- 20 A). We have to find the maximum load that we can connect with the meter.

$Voltage = 250\: V$

$Current = 20\: A$

The maximum load that we can connect will be equal to the power of the electric meter.

The formula for calculating the power is:

$Power = Voltage*Current$

$P = VI$

Substituing the values in the above formula,

$Power = 250*20\: Watts$

$Power = 5000\: W$

Now, we will convert this to kilowatts.

If 1000 W is equal to 1 kW, then 5000 W will be 5 kW.

$1000\: W = 1\: kW$

$5000\: W = 5\: kW$

Hence, we can connect a maximum load of 5 kW.
