General Electric Quiz

What unit of measurement is used to express electrical work?

• • Watt.

• • Joule.

• • Ampere.

• • Ohm.

What unit of measurement is used to express electrical current?

• • Ohm.

• Volt.

• • Watt.

• Ampere.

What unit of measurement is used to express electrical resistance?

• Watt

• Ampere.

Electrical bonding of an aircraft is used to..

• equalise the electrical potential of the different aircraft parts.

• eliminate the need for grounding the aircraft during refuelling.

• prevent the aircraft being struck by lightning.

• ensure the electrical potential of the aircraft structure remains at 0 volts.

The purpose of static wick dischargers is to..

• provide a path to ground for static charges when refuelling.

• dissipate electrical friction allowing the aircraft to fly higher.

• dissipate the static charge from the aircraft`s skin after landing.

• dissipate the static charge of the aircraft in flight.

One indication of inadequate bonding of aircraft components may be:

• interference on the VOR receiver.

• heavy corrosion on the fuselage skin mountings.

• a circuit breaker popping out.

• static noise on the radio.

What unit of measurement is used to express electrical power?

• Ampere.

• Watt.

• Ohm.

• Joule.

The resistors R1 and R2 are connected in parallel. The value of the equivalent resistance (Req) so obtained is given by the following formula:

• 1/Req = 1/R1 + 1/R2

• 1/Req = 1/(R1 + R2)

• Req = R1 x R2

• Req = R1 + R2

Static dischargers:

1. are used to set all the parts of the airframe to the same electrical potential.
2. are placed on wing and tail tips to facilitate electrical discharge.
3. are used to reset the electrostatic potential of the aircraft to a value approximating 0 volts.
4. are located on wing and tail tips to reduce interference with the on-board radio communication systems to a minimum.
5. limit the risks of transfer of electrical charges between the aircraft and the electrified clouds.
