Kanohar Electricals Interview Questions and Answers

Q1. Current and voltage power of diffent
Ans. 
Current and voltage are two key parameters in electrical engineering that determine power consumption.
• Current is the flow of electric charge in a circuit, measured in Amperes (A).

• Voltage is the electrical potential difference between two points in a circuit, measured in Volts (V).

• Power is the rate at which energy is transferred in a circuit, calculated as the product of current and voltage (P = I * V).

• Higher current or...read more

Q2. What is transfor and losess
Ans. 
Transformers are devices used to transfer electrical energy between two or more circuits through electromagnetic induction, while losses refer to the energy dissipated in the transformer due to various factors.
• Transformers are used to step up or step down voltage levels in electrical systems.

• Losses in transformers can be categorized as copper losses (due to resistance in windings) and core losses (due to hysteresis and...read more

Q3. Resistance and capacitor differbt
Ans. 
Resistance and capacitor are two different components in electrical circuits with distinct functions.
• Resistance limits the flow of current in a circuit, while a capacitor stores and releases electrical energy.

• Resistance is measured in ohms (Ω) and depends on the material and dimensions of the component.

• Capacitance is measured in farads (F) and depends on the area and distance between the plates of the capacitor.

• Resista...read more

Q5. What is AC and DC different
Ans. 
AC and DC are two types of electrical current. AC changes direction periodically while DC flows in one direction.
• AC stands for alternating current, which changes direction periodically

• DC stands for direct current, which flows in one direction

• AC is commonly used in household electrical outlets, while DC is used in batteries and electronic devices

• AC can be easily converted to DC using a rectifier

• Examples of AC sources in...read more
