What is a Duty Cycle?
A military term
When someone does their duty
A cycle of rotation

How would you define an analog voltage signal?
Voltage change over time.
Voltage is either on or off.
Voltage is on high one moment, then off or low the next moment.
How would you define a digital voltage signal?
Voltage change over time.
Voltage is either on or off.
Voltage is on high one moment, then gradually moved to low the next moment.
This is an example of a digital signal.
True
False

Decreases
Increases
Stays the same
When mechanical resistance increases, amperage:
Decreases
Increases
Stays the same
When the current to a solenoid or relay is disconnected the magnetic field collapses and causes:
