Current directly proportional to voltage

WebAccording to Ohm's law, the voltage across and current through a resistor are proportional.. If one places a variable resistance (rheostat) across a voltage source, the voltage across the rheostat is fixed.. By fixing the voltage across the rheostat, the current through becomes inversely proportional to the resistance: WebOhm’s law states that for some devices there is a relationship between electric potential difference, current, and resistance. The equation is: I =\dfrac {\Delta V} {R} I = RΔV. Where I I is current, \Delta V ΔV is …
