Electrical Supply

_______ carries electric current to an electrical appliances.

• Neutral wire

• Live wire

• Earth wire

_______ returns electric current to the branch substation.

• Neutral wire

• Live wire

• Earth wire

_______ connects an electrical appliances directly to the Earth.

• Neutral wire

• Live wire

• Earth wire

___________ disconnects the current supply temporarily when it is not needed (such as during repairing damaged wiring).

• ELCB circuit breaker

• MCB circuit breaker

• Main switch

• Electric meter

Since there are multiple pathways the current can take from the positive side of the battery to the negative side, in a ​ (a)   circuit, the ​ (b)   is divided up among the pathways, but the potential, or voltage, is the same for each pathway. ​In ​ (c)   circuits with only one pathway for the current, the ​ (d)   , or voltage, is divided up among the different elements.

• parallel

• current

• series

• potential

What type of circuit is this?
