Given data:
Power transmitted (P) = 2.2 kW = 2200 W
Line resistance (R) = 10 ohms
Transmission voltage (V) = 22,000 V

Step 1: Find the current (I) using the power formula:
P = V * I
Rearranging for I:
I = P / V

Substituting the values:
I = 2200 / 22000
I = 0.1 A

Step 2: Calculate power loss in the transmission line due to heat using Joule's law:
Power loss (P_loss) = I² * R

Substituting the values:
P_loss = (0.1)² * 10
P_loss = 0.01 * 10
P_loss = 0.1 W

Thus, the power loss in the form of heat is 0.1 W.

Dear student 
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  
Good Luck
