Static Charge
What charge does an electron have?
Negative
This is the same at all points
Current
This increases with each loop but is shared across parallel loops
Current
The circuit symbol for a lamp
Circle with an X in it
This equation is known as Ohm's Law
V = I x R
A positive charge and a negative charge will....
Attract
This has to be shared across all components
Potential Difference
If one bulb breaks. How will the other bulbs be affected?
Brighter / Would stay on
This circuit symbol is a blank rectangle
Resistor
Current is the rate of flow of charge. How does that look in an equation?
I = Q / t
This force causes static charge to build up
Friction
Adding more bulbs will make them ______ overall
Darker/Dimmer
This piece of equipment needs to be wired in parallel
Voltmeter
The symbol for the equipment used to measure Potential Difference
Circle with V in it
What is Resistance if Voltage is 9V and Current is 3A?
R = V/I
9/3 = 3 Ohms
Static charge builds up when the _____ move from one material to another
Electrons
In series, Resistance ____ __
Adds up
This decreases and the total is lower than the lowest individual value
Resistance
This symbol is a circle with an arrow inside it. Looks like a play button
Diode
An Ammeter measures 120 Coulombs of charge over a period of 1 minute. What is the current?
120/60 = 2A
Static charge only builds up on these types of materials
Insulators
3+6+2+7 = 18V
Battery has a rating of 10V and two parallel loops with bulbs on them. What is the Potential Difference across 1 bulb?
10V
Describe the circuit symbol for a thermistor
Rectangle with diagonal line through it
Calculate the Power in a circuit with current 5A and Resistance 4 Ohms
P = I2R
P = 52 x 4
P = 25 x 4 = 100W
