IE chapter 1 Quizz

The product of voltage and current is called as                

• EMF
• POWER
• FORCE
• ENERGY

Name the region of operation of a transistor when it is working as a switch.

• Active
• cut off
• Saturation
• cut off & Saturation

The combination of Control system,Electronics and Power system can be called as                 

• Linear Electronics
• Power Electron ics
• Analog Electronics
• Digital Electronics

In the below mentioned circuits which one consumes more power?

• Amplifier
• Mobile charger
• Motor Drives
• Controlled rectifier

Which of the following does not comes under the application of Power Electronics

• Robotics
• Mobile charger
• Motor Drives
• Logic gate

An ideal power diode must have

• low forward current carrying capacity
• large reverse breakdo wn voltage
• high ohmic junction resistance
• high reverse recovery time

To make a signal diode suitable for high current & high voltage carrying applications with minimum losses,                   

• a lightly doped n layer is grown between the two p & n layers
• a heavily doped n layer is grown betwee n the two p & n layers
• a lightly doped p layer is grown between the two p & n layers
• a heavily doped p layer is grown between the two p & n layers

The V-I Characteristics of the diode lie in the

• 1st & 2nd quadrant
• 1st & 3rd quadran t
• 1st & 4th quadrant
• Only in the 1st quadrant

Which of the following is true in case of a power diode with R load?

• I grows almost linearly with V
• I decays almost linearly with V
• I is independent of V
• I initial grows than decays

A diode is said to be reversed biased when the

• cathode is positive with respect to the anode
• anode is positive with respect to the cathode
• cathode is negative with respect to the anode
• both cathode & anode are negative
