- 1The two top and bottom rows on the breadboard we connect the battery are called:Power rails
- 2Explain, in order, what each of the 4 colour bands on the resistor mean?First band-First digit
Second band-second digit
Third band-How many zeroes
Fourth band-tolerance band/"wiggle room" - 3True or False: Anode = positive Electrons flow from negative to positive A photocell is sensitive to light Numbers on wire strippers represent wire thicknessT
T
T
T - 4What are three types of resistors?Common, photocell, potentiometer
- 5How does a potentiometer work in terms of electronics?A variable resistor with a dial that allows us to switch the amount of resistance in the circuit by turning it up and down
- 6How does a diode work in terms of electronics?Electrical component that lets current travel in only one way
- 7What does SCR stand for?Silicon Controlled Rectifier
- 8What are the leads of an SCR called?Cathode Anode Gate
- 9How does a SCR work in terms of electronics?It acts as a fast electronic switch
- 10How does a capacitor work in terms of electronics?Store electrical charge and releases at a later time
Converts AC to DC - 11What is the unit of measurement for capacitance?Farads
- 12How does a transistor work in term of electronics?Part that allows small current to control a large current
- 13What are the three leads of a transistor called?Emitter Base Collector
- 14Why do you need a resistor in front of an LED?LED can only handle a certain amount of current (1.5V) and 9V batteries exceed that limit. You put in the resistor so the LED doesn't burn out
- 15What does the abbreviation for PCB stand for in terms of electronics?Printed Circuit Board
