one-way street |
|
highway |
|
parking lot |
|
traffic light |
A diode allows current to pass easily in one direction and blocks current in the other direction.
Which of the following is not a purpose of a resistor in an electrical circuit?
limit the current in the circuit |
|
control the voltage in the circuit |
|
moderate the heat in the circuit |
|
multiply the current 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 __________ electric current produces a magnetic field proportional to the amount of current flow.
moving |
|
high voltage |
|
low voltage |
|
stationary |
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.
