... A A conductor across which we apply a voltage V = 1 Volt and results in a current i = 1 Ampere is defined as having resistance of 1 Q : Why not use the symbol "O" instead of " " A : Suppose we had a 1000 resistor. We would then write: 1000 O which can easily be mistaken read as 10000 . A condu ...
