- Q1What are the 2 kinds of transistors?PNP and NPNDND and NDNNTN and TNTRNR and NRN30s
- Q2Transistors are made from what?boronaluminumsiliconegallium30s
- Q3How many "legs" are on a transistor?134230s
- Q4what are the names of the 3 "legs" of a transmitter?trans, base, emittercollector, base, transmittercollector, base, emitter30s
- Q5When you plug a trimmer into your breadboard, each pin must NOT connect with a separate row of holes on the breadboard.TrueFalse30s
- Q6What is a voltage divider?When a transistor is connected between a positive and a negative bus.When a potentiometer is connected between the positive bus and the negative bus.When a potentiometer is connected between two negative buses.When a resistor is connected between two positive buses.30s
- Q7Transistors are tough components and they are very hard to burn out.falsetrue30s
- Q8Never apply a power supply directly between any two pins of a transistor. You can burn it out with too much current.FalseTrue30s
- Q9Never limit the current flowing between the collector and the emitter of a transistor by using another component such as a resistor, in the same way you would protect an LED.FalseTrue30s
- Q10Transistors require more power than a relay.TrueFalse30s
- Q11Relays also offer more switching options.FalseTrue30s
