Logical Reasoning: Logical reasoning questions test your ability to identify patterns, analyze sequences, and make deductions based on provided information.

Verbal Reasoning: These questions evaluate your reading comprehension, vocabulary, and language skills. You might encounter passages related to technical topics that you need to understand and answer questions about.

Circuit Analysis: Questions in this category might present you with circuit diagrams and ask you to analyze or solve problems related to circuit components, voltage, current, and resistance

Q1. Can you explain Ohm's Law and how it relates to electrical circuits? What is the difference between AC (Alternating Current) and DC (Direct Current)? Describe the difference between analog and digital si...read more
Ans. 
Ohm's Law relates voltage, current, and resistance in electrical circuits. AC is a changing current direction, while DC is constant. Analog signals are continuous, digital signals are discrete. Power dissipation in a resistor is calculated using P = I^2 * R.
• Ohm's Law states V = I * R, where V is voltage, I is current, and R is resistance.

• AC changes direction periodically, while DC flows in one direction constantly.

• Anal...read more

Q5. Working principle of generator
Ans. 
A generator works on the principle of electromagnetic induction to convert mechanical energy into electrical energy.
• Generators use a magnetic field and a conductor to create a flow of electrons, generating electricity.

• When the conductor moves through the magnetic field, it induces a current in the conductor.

• This current is then collected and transferred through wires to power electrical devices.

• Examples of generators i...read more
