Tata Motors Electronics Engineer Interview Questions, Process, and Tips

Q1. Current and voltage difference
Ans. 
Current is the flow of electric charge, while voltage is the force that drives this flow.
• Current is measured in Amperes (A) and represents the rate of flow of electric charge.

• Voltage is measured in Volts (V) and represents the force or pressure that drives the current.

• Ohm's Law relates current, voltage, and resistance: V = I * R.

• Higher voltage can cause higher current to flow through a circuit.

• Current and voltage have

Q2. What is transformer
Ans. 
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
• Consists of two or more coils of insulated wire wound around a core

• Primary coil receives electrical energy and induces a magnetic field in the core

• Secondary coil receives the magnetic field and converts it back into electrical energy

• Used in power distribution, voltage regulation, and iso...read more

Q3. What is cro and it's principal
Ans. 
CRO stands for Cathode Ray Oscilloscope, a device used to display and analyze the waveform of electrical signals.
• CRO is a type of electronic test instrument that allows observation of constantly varying signal voltages, usually as a two-dimensional plot of one or more signals as a function of time.

• It uses a cathode ray tube (CRT) to display the waveform of the electrical signal.

• CROs are commonly used in laboratories, w...read more

Q1. Not gate definition of plc
Ans. 
A NOT gate in PLC is a logic gate that inverts the input signal, producing the opposite output.
• NOT gate in PLC is used to invert the logic state of the input signal.

• It has only one input and one output.

• The output of a NOT gate is the complement of the input signal.

• For example, if the input signal is ON, the output will be OFF.
