Electron Arithmetic

If two bridges are in series, the AMF is double that of each bridge, and each bridge carries the same traffic

If two bridges are in parallel, the AMF is that of a single bridge, but twice as much traffic can be carried

If two cells are in series, the voltage is doubled but the current is the same as for one cell

If two cells are in parallel, the voltage is the same as for one cell but the current is doubled

Big batteries produce more current than small ones but have the same voltage

You can use many small batteries in parallel in place of one big battery

A collection of cells produces the same power, whether in series or parallel
