The flow of electricity through a circuit

• Closed Circuit

• Open Circuit

• Electric Current

• Magnetic

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 is the same for each pathway. ​In ​ (c)   circuits with only one pathway for the current, the ​ (d)   is divided up among the different elements.
