CORE UNIT MOTOR VEHICLE ELECTRICS

What is an electrolyte?

• A gas that allows electrons to flow freely
• A substance that allows electricity to flow
• The two ends of a battery (positive and negative)
• What separates the charges inside a battery

How is voltage produced in electrochemical cells?

• Two metals are separated by water and electrons flow back and forth (chemical energy)
• Two metals are separated by a conductive material that allows for electrons to flow in one direction (chemical energy)
• Electrons flow back and forth in a battery, the faster they move the more voltage is produced (kinetic energy)
• Two terminals in a battery are separated, the farther the terminals are separated the more work the electrons have to do (potential energy)

The type of current where charges flow in one direction

• Direct Current
• Alternating Current
• Electron Flow
• Voltage

A(n) ______________ is a reusable safety switch that breaks the circuit when the current gets too high.

• Fuse
• Grounded wire
• Fuse box
• Circuit breaker

A device that contains a thin strip of metal that melts easily if the current in the circuit is too high

• Fuses
• Circuit
• Series circuit
• Circuit breaker

A circuit in which the electricity bypasses the resistors and the current increases too much possibly causing the wires to overheat

• Closed circuit
• Short circuit
• Load
• Fuses

The type of current where charges shake back and forth in a circuit

• Alternating Current
• Direct Current
• Voltage 
• Switchback Current

A voltmeter is described as a device that can be used to measure

• Voltage
• Current
• Resistance
• Power

a/an _________ stops the flow of current

• resistor
• capacitor
• insulator
• conductor

the law of static charge states

• like charges repel
• like charges attract
• unlike charges repel
• like charges dont exist
