Question

Using \[P_{\mathrm{loss}}=I^{2}R\], what reduces energy losses during transmission?

Options

• Transmitting at low voltage with larger current \[I\].

• Increasing resistance \[R\] while keeping current \[I\] unchanged.

• Transmitting at high voltage with smaller current \[I\].

• Increasing current \[I\] while keeping resistance \[R\] unchanged.

Answer 1

Transmission losses follow \[P_{\mathrm{loss}}=I^{2}R\]. A smaller current at high voltage therefore produces a smaller loss.
