Resistor is an electronics device made from a straright wire conductor that has capability to resist current flow .

Resistance[edit]

Resistance represents resistor capability to resist current flow . Resistance has a symbol and measured in unit Ohm . According to Ohm's law,

Hence, resistance can be calculated as shown below

Resistor can be made from a straight wire conductor that has resistance of
