Hands on Electricity

Connecting batteries in series

Two batteries add to 3.10 V, three batteries - 4.61 V, and four batteries - 5.25 V.

Kirchhoff's Loop Rule

1.  2.

Electric circuit visible in the first picture will be used to confirm the Kirchhoff's Loop Rule. According to the rule, the voltages around any loop added together give a zero. 

Here are our measurements: - .736 V (see picture #2); .245 V (#3); and .490 V (#4).

- .736 V + .245 V + .490 V = -.001 V
