Technical Questions
1. What are the main differences between AC and DC currents?
AC (Alternating Current) and DC (Direct Current) are two fundamental types of electrical current. The primary difference lies in the direction of flow. AC current changes direction periodically, which is commonly used in power distribution due to its efficiency over long distances, while DC current flows in a single direction, making it ideal for battery-operated devices.
Understanding this fundamental difference helps when working on Tesla's battery technology, which predominantly utilizes DC.
2. Explain Ohm's Law.
Ohm's Law is a principle that relates voltage (V), current (I), and resistance (R) in an electrical circuit, expressed as V = I × R. This law is essential for designing and troubleshooting electrical systems, as it helps predict how variations in resistance or current affect voltage.
3. How do you approach circuit design?
When approaching circuit design, I begin by understanding the project requirements and specifications. I utilize simulation software such as SPICE for initial designs, followed by creating a schematic diagram. Iterative testing and prototyping are crucial to refining the circuit.
4. Describe a time when you had to troubleshoot a complex electrical circuit.
In one project, we faced repeated failures in a prototype's power distribution circuit. I systematically checked each component for issues, ultimately discovering a faulty capacitor. This experience taught me the importance of methodical troubleshooting and the value of comprehensive testing.
5. What is a PCB, and what factors do you consider when designing one?
A PCB (Printed Circuit Board) is a critical component in most electronic devices that supports and connects electrical components. Factors to consider in PCB design include layer count, component placement for signal integrity, thermal management, and manufacturing processes.
Behavioral Questions

12. What are the different types of transformers, and their applications?
There are several types of transformers, such as step-up, step-down, and isolation transformers. Step-up transformers increase voltage for long-distance transmission, while step-down transformers reduce voltage for distribution. Isolation transformers are used for safety and signal integrity.
13. How do you determine the right gauge of wire for a specific application?
When selecting wire gauge, I consider the application's current load, length of the wire run, and acceptable voltage drop. I refer to the American Wire Gauge (AWG) standards to ensure safe and efficient wire sizing.
14. What role do diodes play in electrical circuits?
Diodes allow current to flow in a single direction, acting as rectifiers or protection devices. They are essential in converting AC to DC and preventing reverse current that can damage components.
15. How do you test for continuity in a circuit?
To test for continuity, I use a multimeter set to continuity mode. I touch probes to the circuit points and check for a signal, indicating a complete path for current flow.
