IIT PATNA Interview Questions and Answers

To find faults in a PCB, one can use various techniques such as visual inspection, testing with a multimeter, thermal imaging, and signal tracing.

• Perform a visual inspection to check for any physical damage or loose connections on the PCB.

• Use a multimeter to test the continuity of traces, check for short circuits, and measure component values.

• Utilize thermal imaging to identify hotspots or overheating components that m...read more

Explanation of diode, zener diode, clamp meter, transistor, and resistor color code.

• A diode is an electronic component that allows current to flow in only one direction.

• A zener diode is a type of diode that allows current to flow in reverse direction when a certain voltage is reached.

• A clamp meter is a tool used to measure electrical current without disconnecting the circuit.

• A transistor is a semiconductor device used ...read more
