An electrical circuit requires at least two conductors.

Heavily-loaded circuits may also require a cable size increase to meet voltage drop requirements in wiring regulations.

A complex circuit like an adder would generally require several modules working in concert.

On June 28, 2007, a short circuit caused a fire in the transformer of the power plant and required the plant to be shut down.

Riding circuit required physical abilities that she didn't have, but that didn't matter.

Under standby conditions, the circuit requires 20mA approximately and while operating the solenoid valve, 200mA.

All electrical circuits require a closed loop, whether explicit through wiring, or implied through a common ground.

Some circuits require all LD judges for rounds above the novice level to meet training requirements.

These resulting circuits were faster but required more area on the chip.

These wide-band circuits require very fast encryption systems.
