Question

if 2.2 kilowatt power is transmitted through a 10 ohm line at 22000 volt the power loss in the form of heat will
​

Answer 1

Answer: Hi ___

P=2.2 kW

R = 10 ohm

V= 22000 V

Power loss, P= i square R

P= p by v whole square cross R

Substitute the values,

P= 0.1 W

Explanation:

Answer 2

The power loss in the form of heat is 0.1 W

Explanation:

It is given that,

Power, P = 2.2 kW = 2200 W

Resistance, R = 10 ohms

Voltage, V = 22000 v

We need to find the power loss in the form of heat. It is given by :

$P_L=I^2 R$

I is the current

Power in the form of voltage and current is given by :

P = V I

$P_L=\dfrac{P^2R}{V^2}$

$P_L=\dfrac{(2200)^2\times 10}{(22000)^2}$

$P_L=0.1\ W$

So, the power loss in the form of heat is 0.1 W. Hence, this is the required solution.
