Connecting the 6 batteries in series multiplies their voltage while keeping their current the same yielding a 36V 5A configuration. Connecting the 6 batteries in parallel multiplies their current while keeping their voltage the same yieleding a 6V 30A configuration. Using a series-parallel connection, 3 batteries can be connected in series and 3 can be connected in parallel resulting in a 18V 15A configuration.
General current flow in a transistor is from __________ to __________.
collector, emitter |
|
collector, base |
|
base, collector |
|
base, emitter |
The transistor is the foundation of modern electronic devices. It is made entirely from semiconductor material (making it a solid state device) and can serve many different functions in a circuit including acting as a switch, amplifier, or current regulator. A transistor works by allowing a small amount of current applied at the base to control general current flow from collector to emitter through the transistor.

Longer the electrical wires mean _______________ voltage drop.
greater |
|
lesser |
|
diminishing |
|
complete |
Electrical wires have a certain amount of resistance per foot. A longer wire means more resistance and a greater voltage drop.
The formula specifying Ohm's law is which of the following?
\(V = {R \over I}\) |
|
V = IR |
|
V = I2R |
|
\(V = {I \over R}\) |
Ohm's law specifies the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit: V = IR.
