Question

write mathematical expression for kirchoffs law​

Answer 1

Answer:

Kirchhoff’s Second Law or the voltage law states that

The net electromotive force around a closed circuit loop is equal to the sum of potential drops around the loop

It is termed as Kirchhoff’s Loop Rule, which is an outcome of an electrostatic field that is conservative.

Hence,

If a charge moves around a closed loop in a circuit, it must gain as much energy as it loses.

The above can be summarized as the gain in energy by the charge = corresponding losses in energy through resistances

Mathematically, the total voltage in a closed loop of a circuit is expressed as ∑V=0.

The below figure illustrates that the total voltage around a closed loop must be zero.

do you want the current law too
