Nissi Engineering Solution Testing & Commissioning Engineer Interview Questions and Answers

Impedance is the measure of opposition to the flow of alternating current in a circuit.

• Impedance is a combination of resistance and reactance in a circuit.

• It is measured in ohms (Ω).

• Impedance can be calculated using the formula Z = √(R^2 + X^2), where R is resistance and X is reactance.

• Impedance is important in determining the behavior of circuits in AC systems.

• Examples of components with impedance include resistors, c

KCL and KVL are fundamental laws in electrical engineering used to analyze circuits.

• KCL (Kirchhoff's Current Law) states that the total current entering a node is equal to the total current leaving the node.

• KVL (Kirchhoff's Voltage Law) states that the sum of voltages around a closed loop in a circuit is zero.

• KCL is based on the principle of conservation of charge, while KVL is based on the principle of conservation of...read more
