Resistance+(Ohm's+Law)

=Ohm's law explains the relationship between current, coltage and resistance. It is an important concept as it allows us to calculate things like the resistance in an electrical circuit. An example would be how to reduce the amount of resistance in powerlines.=

=Below are the formula that we used in class. you must be confident using the triangle to find the correct formula, and then use this to perform calculations.=



n **V** = **I x R (Voltage = Current multiplied by Resistance)** n **R** = **V / I (Resistance = Voltage divided by Current)** n **I** = **V / R (Current = Voltage Divided by Resistance)**
