I appeared for an interview before Apr 2024, where I was asked the following questions.
- Q1. What is the purpose of a neutral wire?
- Ans.
The neutral wire completes an electrical circuit by providing a return path for current, ensuring safety and proper functioning.
The neutral wire carries current away from the load back to the power source.
It is typically color-coded white or gray in electrical systems.
In a balanced system, the neutral wire helps maintain voltage levels.
Example: In a household circuit, the neutral wire allows appliances to operate safel...
- Q2. What are the differences between series and parallel connections?
- Ans.
Series connections have components in a single path, while parallel connections have multiple paths for current flow.
In series, current is the same through all components; in parallel, voltage is the same across all branches.
Example of series: Christmas lights; if one bulb fails, the entire string goes out.
Example of parallel: Household wiring; if one appliance fails, others can still operate.
In series, total resistanc...
- Q3. What is the color sequence of a three-phase system, and what is the degree difference between two phases?
- Ans.
A three-phase system typically follows a color sequence and has a 120-degree phase difference between each phase.
Common color sequence: Red, Yellow, Blue.
Phase A (Red) leads Phase B (Yellow) by 120 degrees.
Phase B (Yellow) leads Phase C (Blue) by 120 degrees.
Phase C (Blue) leads Phase A (Red) by 120 degrees.
This 120-degree separation helps in balanced load distribution.
