### Ohms law added by arvi

1. 1. Ohm’s Law explains the relationship between voltage (V or E), current (I) and resistance (R) Used by electricians, automotive technicians, stereo installers
2. 2. Ohm’s Law E I= R Where: I = current (amperes, A) E = voltage (volts, V) R = resistance (ohms, Ω)
3. 3. Ohm’s Law: Resistance and Resistors In many conductors, the resistance is independent of the voltage; this relationship is called Ohm’s law. Materials that do not follow Ohm’s law are called non-ohmic. Unit of resistance: the ohm, Ω. 1 Ω = 1 V/A.
4. 4. It is the push or pressure behind current flow through a circuit, and is measured in (V) volts.
5. 5. Current refers to the quantity/volume of electrical flow. Measured in Amps (A)
6. 6.  Resistance to the flow of the current. Measured in Ohms
7. 7. 1. 2. 3. 4. 5. 6. 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.
8. 8. V (E) = I x R I=V R R=V I
