a) Battery Electric Vehicle (BEV) b) Hybrid Electric Vehicle (HEV) c) Plug-in Hybrid Electric Vehicle (PHEV) d) All of the above Correct Answer: d) All of the above Explanation: All three are distinct types of electrified vehicles BEVs run solely on batteries, HEVs use both an engine and electric motor without plug-in capability, and PHEVs have plug-in capability with both power sources
Section 2: Electricity Fundamentals (Questions 21-45)
Question 21 Voltage is defined as: a) The flow of electrons through a conductor b) The pressure that pushes electrons through a conductor c) The opposition to the flow of electrons d) The power consumed by a device Correct Answer: b) The pressure that pushes electrons through a conductor Explanation: Voltage is the electrical pressure or potential difference that drives current through a circuit It is measured in volts and is analogous to water pressure in a pipe
a) V = I x R b) P = V x I c) I = V x R d) V = P x I Correct Answer: a) V = I x R Explanation: Ohm's Law establishes the relationship between voltage, current, and resistance Voltage equals current multiplied by resistance This is fundamental to understanding electrical circuits Question 25 In a series circuit, which of the following is true? a) The voltage is the same across each component b) The current is the same through each component c) The resistance is the same for each component d) None of the above Correct Answer: b) The current is the same through each component Explanation: In a series circuit, the same current flows through each component because there is only one path for current to flow Voltage divides across the components based on their resistance Question 26 Power is calculated using which formula?
