Question

Power losses in transmission lines occur due to heating. This is calculated using the formula : ___

• A. $I^{2}R$
• B. $V^{2}R$
• C. $\frac{I}{R}$
• D. $\frac{I^2}{R}$

Answer 1

The correct option is A $I^{2}R$

Power losses in transmission lines occur due to heating. This is calculated using the formula: $I^{2}R$, where I is the transmission current and R is the resistance of the line.
