Electrics level 2

The unit of electrical power is the:

• Volt

• Amp

• Coulomb

• Watt

A high resistance in the battery earth connection will cause the earth to lead to:

• Glow in the dark

• Become loose on the terminal

• Freeze in cold weather

• Get hot when starting the engine

When removing or repairing electronic communication systems or components it is advisable to:

• Use plastic tools

• Disconnect the battery first

• Make sure the battery is fully charged

• Earth yourself to the car to discharge static electricity before starting the task

The fault shown on the electrical diagram is?

• A blown bulb

• A faulty earth

• An open circuit

If you were to connect the leads of an ammeter directly to the terminals of a battery:

• It would read 12 amps

• It would read 12 volts

• You can judge the battery condition

• It would seriously damage the meter
