Series Circuits - In the "Series Circuit", there is only one path for the current to take. The diagram above shows a battery (consisting of 2 cells) connected to 2 cells wired in series. If one of the bulbs in the circuit fails (blows), then the circuit will be open and current will stop flowing.

1. How many amps in the circuit? 6 amps

2. How many amps at A and A2? 3 amps

3. How many amps at 2, 3, 4? 10 amps

Parallel Circuits - In a "Parallel Circuit", the current has more than one way of moving around the circuit. If one of the bulbs fails (blows), the other one will still have a current through it and will still glow. 

1. A1 and A2 have two amps because the 4 amps are halved = 7 amps

A1 = 3 amps

A2 = 4 amps

2. 3A + A2 + A1 = 6 amps 

A1= 3 amps

A2= 3 amps

3. A1 = 1 amps 

A2 = 4 Amps

A3 = 12 Amps
