Words and meanings to learn
National Grid
a network of cables and transformers that transfers electrical power from power stations to consumers across the country
step-down transformer
a device that decreases the voltage of electricity to a safer level for domestic or business use
potential difference (voltage)
the energy transferred per unit charge in an electric circuit, measured in volts (V)
base load
the minimum level of continuous electricity demand supplied by large, efficient power stations running constantly
step-up transformer
a device that increases the voltage of electricity for efficient transmission over long distances by reducing current and energy loss
