IMI Electrical revision

The relative density of the electrolyte in a fully charged lead acid battery is approximately:

• 12.80

• 1.300

• 1.500

• 1.280

• None of the above

In the image the component is known as a:

• Diode

• Capacitor

• Fuse

• Transistor

The unit of electrical power is the:

• Voltage

• BHP

• Newton

• Watt

A thermistor is a type of:

• Electronic one way valve

• Rectification diode

• Suppression device

• Temperature sensitive device

What type of starter is shown:

• Inertia drive

• Engaged drive

In a lead acid battery, distilled water and sulphuric acid are mixed together to make:

• H2SO4

• PB04

• 2H2SO4

• H2O4

What check would you carry out, if the door window motor does not work?

• Replace the motor

• Replace the operating switch

• Check the fuse

• Measure the operating current

When fitting a halogen head lamp bulb you should:

• Test the bulb before fitting it

• Clean the reflector

• Avoid touching the glass envelope

• Check the beam setting after fitting the bulb

The diagram shows part of a lighting circuit. What is the effect if the earth connection to the component labelled 'C' is broken?

• The sides light will not operate

• The dip beam will not operate

• It will make no difference

• Both dip and main will not operate but the headlamp flash will work

A permanent live feed is found at point A on the electrical diagram and this would cause:

• The starter will operate as normal

• The starter will not operate

• The starter will operate erratically

• The starter will permanently rotate
