Electromotive force is another name for:
current |
|
power |
|
energy |
|
voltage |
Voltage (V) is the electrical potential difference between two points. Electrons will flow as current from areas of high potential (concentration of electrons) to areas of low potential. Voltage and current are directly proportional in that the higher the voltage applied to a conductor the higher the current that will result.
The most common circuit configuration is:
household |
|
series-parallel |
|
parallel |
|
series |
Circuits are not limited to only series or only parallel configurations. Most circuits contain a mix of series and parallel segments. A good example is a household circuit breaker. Electrical outlets in each section of the house are wired in parallel with the circuit breaker for that section wired in series making it easy to cut off electricity to the parallel parts of the circuit when needed.
What is the primary difference between a rectifier and an inverter?
a rectifier converts an AC input to DC while an inverter converts a DC input to AC |
|
a rectifier strips out the DC portion of electricity while an inverter strips out the AC portion |
|
a rectifier strips out the AC portion of electricity while an inverter strips out the DC portion |
|
a rectifier converts a DC input to AC while an inverter converts an AC input to DC |
A diode allows current to pass easily in one direction and blocks current in the other direction. Diodes are commonly used for rectification which is the conversion of alternating current (AC) into direct current (DC). Because a diode only allows current flow in one direction, it will pass either the upper or lower half of AC waves (half-wave rectification) creating pulsating DC. Multiple diodes can be connected together to utilize both halves of the AC signal in full-wave rectification.

| 36V 80A | |
| 9V 160A | |
| 72V 20A | |
| 72V 160A |
Connecting the 8 batteries in series multiplies their voltage while keeping their current the same yielding a 72V 20A configuration. Connecting the 8 batteries in parallel multiplies their current while keeping their voltage the same yielding a 9V 160A configuration. Using a series-parallel connection, 4 batteries can be connected in series and 4 can be connected in parallel resulting in a 36V 80A configuration.
