Electricity
Resistance
How difficult it is for current to flow
Bigger the resistance the smaller the current
Resistance is measured in Ohms (n)
V = I x R
R = Reluctance (n)
I = Amps (Current)
V = Potential Difference
Electrical Current
Flow of electricity charge
Measured in Amps
Q = Charge (Coulombs)
Q = I x T
I = Current (Amps)
T = Time (Seconds)
Thermistors
Used in a thermostat
Temperature affected resistors
LBR (Light Dependent Resistor)
Street lights
Parallel circuit
More than one loop - current can take more than 1 route
Series circuits
One loop - current can only take 1 route around the circuit
