a light sensitive resistor
A
photoresistor
4
Q
current is measured in
A
amperes
5
Q
LED stands for
A
light emitting diode
6
Q
the rate of doing work
A
power
7
Q
Basic formula for Power
A
P= V x I (Power = voltage x current)
8
Q
Basic forumla for current
A
I = V/ R (Current = voltage / resistance)
9
Q
Resistance forumla
A
R= Voltage/Current (Resistance = voltage / current)
10
Q
Ohm’s law
A
voltage = resistance x current (v = r x i)
