1.Parallel Arrangement
The four batteries in
parallel in the upper diagram produces the voltage in one cell and they will
supply the current four times of it.Current is the rate at which
electric charge passes through a circuit, and is measured in amperes. Batteries
are rated in amp-hours, or, in the case of smaller household batteries,
milliamp-hours (mAH). A typical household cell rated at 500 milliamp-hours
should be able to supply 500 milliamps of current to the load for one hour. You
can slice and dice the milliamp-hour rating in lots of different ways. A 500
milliamp-hour battery could also produce 5 milliamps for 100 hours, 10
milliamps for 50 hours, or, theoretically, 1,000 milliamps for 30 minutes.
Generally speaking, batteries with higher amp-hour ratings have greater
capacities.
2.Serial Arrangement
The four batteries in
series in the upper diagram produces the current in one cell and they will
supply the voltage four times of it.Voltage is a measure of energy
per unit charge and is measured in volts. In a battery, voltage determines how
strongly electrons are pushed through a circuit, much like pressure determines
how strongly water is pushed through a hose. Most AAA, AA, C and D batteries
are around 1.5 volts.
Imagine the batteries shown in the diagram are rated at 1.5
volts and 500 milliamp-hours. The four batteries in parallel arrangement will
produce 1.5 volts at 2,000 milliamp-hours. The four batteries arranged in a
series will produce 6 volts at 500 milliamp-hours
