Voltage - Current relationship in a DC circuit
wn in this relation, V represent voltage which is the potential difference across the two ends of a electrical conductor and between which an electric current, I, will flow. The constant, R, is called ... it directly provided that the remaining variable V and I is known. A resistor is a piece of electric conductor which obeys Ohm's Law and has been designed to have a specific value for its resi ...
