Resistor is an electronics device made from a straright wire conductor that has capability to resist current flow .
Resistance[edit | edit source]
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
