How many valence electrons does an insulator, semiconductor, and conductor have?

-8 -4 -1

Single-element semiconductors are characterized by atoms with ________valence electrons

4

Convert the binary number 1001.0010 base 2 to decimal

9.125

The truth table for a 2 inputs XOR is: WHERE A and B are inputs and X is output

A B X 0 0 0 0 1 1 1 0 1 1 1 0

The expression X=A+B means

A OR B

A logic gate that produces a HIGH output only when all of its inputs are HIGH is a(n)

AND Gate

An electronic circuit that coverts ac into dc pulsating dc: one part of a power supply is

Rectifier

A 2-input gate produces a HIGH output only when the inputs agree. This type of gate is a(n)

XNOR gate

The movement of free electrons in a conductor is called

current

Under normal conditions a diode conducts current when it is

forward-biased

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

increase

When a pn junction is formed, eletrons move across the junction and fill holes in the p-region. the filled hole is a

negative ion

A diode conducts when it is forward-biased, and the anode is connected to the________through a limiting resistor.

posititive supply

A silicon diode measures a low value of of resistance with the meter leads in both positions. The trouble, if any, is

the diode is working correctly
