Question 1: How do you ensure that the electrical power system of an electric vehicle is both efficient and safe?

Which action should you take?

Choose only one option

By designing for minimal power loss, using high-efficiency components, and implementing robust protection systems

By reducing the number of components to save space

By focusing solely on maximizing the power output

By using a one-size-fits-all approach to system design

Question 2: How do you design a circuit that can handle both AC and DC power sources in automotive applications?

Which action should you take?

Choose only one option

By using appropriate rectifiers and inverters, along with proper switching components

By using only AC sources for automotive systems
