ohms law

Ohms law calculator: Famous German physicist G.S Ohm explained Ohm’s  law. In 1826 he explained flowing of current I and potential difference V through a conductor is constant. At a fixed temperature if current flows over a conductor then voltage is proportional to current.

R= V/ I

Consider, AB is a conductor.

Potential difference of A and B are V_A and V_B.

If  V_A > V_B

Potential difference = V_A - V_B

= V

Current flows from A to B point.

According to Ohm’s law,

Here G is constant. G is the conductance of conductor.

G is inversely related to resistance R.

G = I / R

Putting value in equation (i)

I = GV

= V / R

= V / R

So, V = IR

This is the ohms law equation.
