B - Electrical Circuits Flashcards
The following symbol is a:
Rheostat
The following image is a/an:
Motor.
A break in the normal path of an electric circuit causes a/an:
Open circuit.
The amount of current in a circuit is determined by:
Source voltage and resistance of the circuit.
If an open occurs in a circuit, current:
Decreases.
As applied voltage increases:
Current increases.
Voltage is:
Potential difference.
Resistance is:
Determined by circuit construction.
Amperage is:
Measurement of current flow.
Resistance of a circuit decreases if a/an:
Short occurs in a series or parallel circuit.
As resistance of a circuit increases:
Current decreases.
If a resistor in a circuit is shorted, an ammeter in the circuit would indicate:
More current than normal.
In heavy equipment’s electrical syste, a resisitor could be:
A light bulb, a two-way radio, or a starter motor.
Reduced current flow ina series circuit can be caused by:
Corroded terminals in a battery.
