3. Cells In Series
When you have more than one battery, you can put the batteries in series. That is putting the batteries end to end in a line.
When the cells are connected in series, the voltage __________
When the cells are connected in series, the lights get __________

4. Cells in Series Drawing cells in series in circuit diagrams:
3 batteries
1 battery
2 batteries

6. Cells in Parallel
When you have more than one battery, the batteries can be connected in parallel. That is putting the cells side by side, in the same orientation and connecting them all together.
When the batteries are in parallel, the positive ends have to be on the same side for all batteries. Example: OR

7. Cells in Parallel
