Electrical basics

If a short to____ occurs before a load, that load will not function

• power

• open

• resistance

• ground

Low resistance in a circuit can damage circuit components

• True

• False

____ are used to complete or interrupt a current path

• terminals

• connectors

• switches

• wires

In a series parrallel circuit with a 12v source and a series load with a voltage drop of 7 volts, having the same resistance what will the voltage drop be across each of the parallel loads?

• 2.5 volts

• 7 volts

• 12 volts

• 5 volts

If resistance is too high, which of the following may not occur

• a bulb may light dimly

• a bulb may not light at all

• a bulb may blow out

• a motor may run slowly

An open in one branch of a parallel circuit will

• cause failure in current flow in all branches

• cause failure of current flow in the branch which is open

• cause the fuse to blow

• cause no problems

When performinga voltage drop test, the circuit must be

• Off (not working)

• disconnected

• On (working)

• connected

Voltage is sometimes also referred to as electrical_____

• Current

• volts

• water

• pressure

Which of the following cannot cause an open circuit

• loose connection

• corroded connections

• all the above

• broken wires

In a series circuit, what happens when a new load is added

• Voltage increases

• current goes up

• Voltage splits between loads

• Source voltage decreases
