What component does this schematic represent?
Resistor
Photocell/Photoresistor
Potentiometer
Diode
Which component is place incorrectly?
Hint: look at the battery to find the direction of positive and negative, then check the components.
Resistor
Capacitor
Diode
All the above/the battery
What component is this?
Photocell/Photoresistor
LED
PNP transistor
NPN transistor
Which of the following are kinds of resistors? (select all that apply)
Diode
Capacitor
Potentiometer
Photocell
Speaker
A resistor with the color code RED-BLUE-BROWN-SILVER has how much resistance?
260Ω
1500Ω
2600Ω
270Ω
In the selected space on the circuit, which direction should the Capacitor go? A or B?
A
B
Either Works
Which kind of current can be "stepped" up or down to a desired voltage?
Alternative Current (AC)
Direct Current (DC)
Both
Neither
If I know the value of R1, R2, and R3, how would I calculate Total Resistance?
Total Resistance = R1 + R2 + R3
Total Resistance = 1/R1 + 1/R2 + 1/R3
Total Resistance = 1/ (1/R1 + 1/R2 + 1/R3)
Total Resistance = 1/(R1 + R2 + R3)
What is the power of a circuit with a voltage of 6V and a current of .5A?
2 Watts
10 Watts
3 Watts
Not enough information
What component is this?
LED
Potentiometer
Normally Open (NO) Switch
Normally Closed (NC) Switch
What component is this?
Diode
NPN transistor
PNP transistor
Capacitor
If we are given Resistance Total and the Current at point 1, how would we find the Voltage at R2?
We don't have enough information to find Voltage at R2.
Voltage will be the same as Voltage total, because Voltage loops. So V = I * R
Voltage = Current minus Resistance
Voltage = Current divided by Resistance
How would we calculate the current going through the 8V resistor if we are given current at A and D?
We would subtract current at D from current at A
We would add current at D to current at A
We would multiple current at D by current at A
We don't have enough information to find the current going through that resistor
What component is this?
Normally Closed (NC) Switch
Potentiometer
Speaker
Normally Open (NO) Switch
