Natiijada casharka
I can describe the National Grid and explain why transmission lines use a very high transmission voltage.
Muuji qoraalka
Power is transferred by electricity from power stations to consumers using the National Grid.
Step-up transformers increase the transmission voltage from a power station to the transmission line.
Step-down transformers decrease the transmission voltage from a transmission line to the consumer.
Transmission lines dissipate some energy by heating (P = I²R).
A very high transmission voltage reduces transmission current and the heating of transmission lines.
