Connecting the 6 batteries in series multiplies their voltage while keeping their current the same yielding a 36V 10A configuration. Connecting the 6 batteries in parallel multiplies their current while keeping their voltage the same yieleding a 6V 60A configuration. Using a series-parallel connection, 3 batteries can be connected in series and 3 can be connected in parallel resulting in a 18V 30A configuration.
Which of the following will increase the magnetic field produced by the electric current in a wire?
construct the wire from conductive material |
|
wind the wire into a coil |
|
wrap the wire around a ceramic core |
|
construct the wire from insulative material |
A moving electric current produces a magnetic field proportional to the amount of current flow. This magnetic field can be made stronger by winding the wire into a coil and further enhanced if done around an iron containing (ferrous) core.
Which of the following is not a purpose of a resistor in an electrical circuit?
multiply the current in the circuit |
|
limit the current in the circuit |
|
control the voltage in the circuit |
|
moderate the heat in the circuit |
Resistors can be chosen in a wide variety of values to control the voltage in a circuit, limit the current, or moderate the heat produced by the components in the circuit.
A transistor to an electronic circuit is like a _______________ to a house?
no trespassing sign |
|
gate |
|
driveway |
|
safe |
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. A transistor acts as a gate or switch for electronic signals.
This circuit component symbol represents a(n):

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.
