Ohms law

Ohms law

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

V ∞ I

V = I R

Here R is the resistance

What do Kirchhoff’s laws state?

• Kirchhoff’s Current Law goes by several names as Kirchhoff’s First Law and Kirchhoff’s Junction Rule. According to the Junction rule, in a circuit, the total of the currents in a junction is equal to the sum of currents outside the junction.Kirchhoff’s Voltage Law goes by several names as Kirchhoff’s Second Law and Kirchhoff’s Loop Rule. According to the loop rule, the sum of the voltages around the closed loop is equal to null.
