A diode can conduct current in two directions with equal ease

• True

• False

A diode conducts current when forward biased

• True

• False

When reverse biased, a diode ideally appears as a short.

• True

• False

When a diode is forward biased and the bias voltage is increased, the forward current will

• increase

• decrease

• not change

The term bias means

• the ratio of majority carriers to minority carriers

• the amount of current across the diode

• a dc voltage is applied to control the operation of a device

• neither (a),(b), nor (c)

A reverse-biased diode will act as an

• closed switch

• open switch

• both open and closed switch

• none of the options

The characteristic curve of the diode shows the relation between

• Current and Voltage

• Voltage and resistance

• Voltage and Power

• Resistance and Temperature

For a silicon diode, the value of the forward bias voltage typically

• must be greater than 0.3V

• must be greater than 0.7V

• depends on the width of the depletion region

• depends on the concerntration of majority carriers

A diode is normally operated in

• reverse breakdown

• the forward bias region

• the reverse bias region

• either (b) or (c)

Ideally, a diode can be represented by a

• voltage source

• resistance

• switch

• all of these
