WebA potential difference of 2 V exists across a potentiometer wire of 2 m length. When the potential difference across a 2 Ω resistance of a second circuit is measured by the potentiometer wire, it amounts to 5 m m balancing length. The current in the second circuit is WebOhm’s Law. Ohm’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 electric potential difference, and R R is … I think that Kirchhoff's junction rule is a bit unclear about the fact that while the … Device used to reduce current flow.
