describe how an electrical circuit works.
user
an electrical circuit is a closed loop of conducting wires. when a source of electricity is connected to the circuit, such as a battery, current flows around the loop. this current is able to power electrical components, such as bulbs, within the circuit. the electricity also encounters any resistance components, such as a resistor, which cause the current to decrease. the current then returns to its source, completing the circuit.
