Expert Electrical Engineering Interview Questions and Answers

Q:Define Kirchhoff’s laws.

A: Kirchhoff’s laws consist of two rules essential in circuit analysis. Kirchhoff's Current Law (KCL) states that the total current entering a junction equals the total current leaving it. Kirchhoff's Voltage Law (KVL) says that the sum of all electrical voltages around a loop is zero

Q:What are the types of electrical circuits?

A: Electrical circuits can be classified into series, parallel, and series-parallel circuits. In a series circuit, components are connected end-to-end, so the same current flows through each component. In a parallel circuit, components are connected across the same voltage source, so the voltage is the same across each component. Series-parallel circuits combine elements of both.

Q: What is Ohm’s Law?

A: Ohm's Law is a fundamental principle in electrical engineering, stating that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature remains constant. The formula is I = V/R, where I is the current, V is the voltage, and R is the resistance.

Q) What is a Transformer?
A) transformer transfers electrical energy between circuits using electromagnetic induction.

Q: What is electric power?

A: electric Power is the rate at which electrical energy is transferred by an electric circuit, measured in watts (W)

Q) What is a resistance?
A) Resistance is the opposition to the flow of electric current, measured in ohms (Ω)
