Lesson 1 Electrics Quiz

What is the charge of protons in an atom?

• Negatively (-) charged

• No charge

• Positively (+) charged

• Variable charge

What particles in an atom have no charge?

• Protons

• Neutrons

• Free electrons

• Nucleus

Which part of the atom contains the protons and neutrons?

• Free electrons

• Nucleus

• Outer orbit

• Electron cloud

What are free electrons?

• Positively (+) charged particles

• Particles with no charge

• Negatively (-) charged particles

• Particles found in the nucleus

What happens when a circuit is completed?

• The positively charged free electrons are attracted to the negative terminal of the battery.

• The negatively charged free electrons are repelled by the positive terminal of the battery.

• The negatively charged free electrons are attracted to the positive terminal of the battery.

• The circuit breaks and no electrons move.

What happens when the bulb is introduced into the circuit?

• The bulb accelerates the flow of electrons

• The bulb allows electrons to flow without resistance

• The bulb resists the flow of electrons, causing it to heat up and glow

• The bulb converts electron flow directly into sound

Which of the following is NOT a unit of electricity commonly used in vehicles?

• Coulomb

• Amp

• Ohm

• Watt

What is the unit of frequency used in the context of electricity in vehicles?

• Volt

• Amp

• Hertz

• Farad

Why is it important to be aware of units of electricity such as Volt, Amp, Ohm, Hertz, Watt, and Farad?

• They are used to measure fuel efficiency.

• They are important when working with and diagnosing electrical circuit faults.

• They are only relevant for electric vehicles.

• They are used to measure the speed of a vehicle.

Which of the following is an example of electricity generation through chemical reaction in the motor vehicle industry?

• Through an alternator

• Vehicle battery

• Knock sensors

• Through the Crankshaft Position Sensor
