In an n type semiconductor the majority carriers are:

• 1 Neutrons
• 2 Holes
• 3 Electrons
• 4 Protons

A p n junction diode conducts when it is:

• 1 Heated only
• 2 Reverse biased
• 3 Forward biased
• 4 Never

A transistor can act as an:

• 1 Only a resistor
• 2 Amplifier or a switch
• 3 Only a battery
• 4 Only a capacitor

An operational amplifier has an ideal input resistance of:

• 1 Zero
• 2 1 ohm
• 3 100 ohm
• 4 Infinity

A NAND gate output is 0 only when:

• 1 Both inputs are 1
• 2 Both inputs are 0
• 3 Inputs differ
• 4 Any input is 1
