A Resistance is the degree to which a substance or device opposes the passage of an electric current, causing energy dissipation. Ohm's law resistance is equal to the voltage divided by the current.

a resistor or other circuit component that opposes the passage of an electric current. Resistance is measured in Ohm's. Resistance is equal to the V (voltage) over I (current) R=V/I. Voltage is Measured in Volts and I the current is measured in amps. Resistance also equals (resistivity)(Length)/ Pie(radius) Squared. or R=pL/pier^2. Resistance also equals power divided by Current squared or R=P/I^2. In a series circuit equilibrium resistance all adds up. in a parallel circuit it is 1/Req=1/R+ 1/R. you can find out more about this information on your reference table .
