1
It is the push or pressure behind current flow through a circuit, and is measured in (V) volts.
2
Current refers to the quantity/volume of electrical flow. Measured in Amps (A)
3
Resistance to the flow of the current. Measured in Ohms
5
1. Assuming the resistance does not change: As voltage increases, current increases. as voltage decreases, current decreases. 2. Assuming the voltage does not change: As resistance increases, current decreases. As resistance decreases, current increases.
6
Studied the relationship between voltage, current, and resistance.
7
Ohm’s Law explains the relationship between voltage (V or E), current (I) and resistance (R) Used by electricians, automotive technicians, stereo installers
9
V = I x R I = V R R = V I
10
A circuit has a current of 12 amps and a resistance Of 5 Ohms. What is the voltage? 12 x5 = 60 V
11
Battery voltage is 12V Resistance 2 Ohm What is the current? 12 / 2 = 6 amps
12
Voltage is 12V Current is 4 Amps What is the resistance? 12 / 4 = 3 ohms
13
What is Voltage? What is Current? What is Resistance? http://www.youtube.com/watch?v=nj7ewZmG3 eo&feature=related
14
Series circuit : One pathway for current to flow. Example: Old Christmas lights
15
More then one path way for current to flow. Used in most electrical vehicle circuits.
