Definitions
What is current?
The flow of electrons through a circuit - think of this as a train with many cars riding a single track.
What unit is voltage measured in?
Volts!
What two variables are multiplied together to find voltage?
According to Ohm's law...
Current * Resistance = Voltage
What is voltage a measure of?
The difference in electrical potential energy in a circuit - sort of like kicking a football, think of voltage like your foot - the provider of force to the football (think of the football as the electrons), thus causing the football or electrons to move.
What is the variable I measured in?
Amps!
How can I find current with the values:
R = 6
V = 7
I = (7/6) or Voltage/Resistance
What is an analogy for resistance?
Sharp vs. Dull Scissors - think of resistance in this way:
- Think of less resistance like sharp scissors. More paper can be cut with less effort (or current can flow easier) with sharp scissors or with less resistance.
What unit can be found with the following values:
2 Volts (v)
3 Amps (a)
Ohms or Resistance!
How can I find the resistance of a circuit with the values: V = 1 and I = 2
AND
What famous logo is the Ohms symbol shaped like?
R = V/I
Ohms symbol is similar to the Lululemon logo!
