EV Quiz

The purpose of Ohm’s Law is to calculate the relationship between:

• Current, Charging and Power

• Power, Acceleration and Amps

• Voltage, Currents, and Resistance

• Power, Consumption and Voltage

Increasing the cross-sectional area of wire, or the number of strands of wire in a cable:

• Increases electrical resistance to flow

• Increases maximum current flow capability

• Decreases potential flow of data information

• Decreases maximum voltage potential capability

Why are the HV cable is orange in colour?

An EV air conditioning compressor may represent additional hazards because:

• It can be made of expensive materials

• It can be part of the low voltage system

• It can be part of the high voltage system

• It can be difficult to access in the engine bay

If an electric/hybrid is involved in an accident, what is the first step to safeguard the vehicle and ensure technician safety?

• Locate the main power switch and turn to the off position

• Locate the inertia switch and operate to immobilise the system

• None, system will automatically switch off the high energy electrical system

• Carry out vehicle visual inspection and seek further assistance before commencing
