JBCO Powertech Interview Questions and Answers

Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance.

• Ohm's law is expressed as: V = I * R

• V represents voltage in volts, I represents current in amperes, and R represents resistance in ohms.

• According to Ohm's law, if the voltage is increased while the resistance remains constant, the current will also increase...read more

The AB switch is rated based on its performance and reliability. Fuses are used to protect electrical circuits from overcurrent.

• The rating of an AB switch indicates its capacity to handle electrical load and switching operations.

• Higher ratings indicate better performance and reliability.

• Fuses are essential components in electrical circuits to protect against overcurrent.

• Fuses have specific current ratings that determin...read more
