- The transfer function of a system can be defined as the value by which if the input is multiplied, we will get the response of the system.

- Above diagram shows an electrical system which consists of voltage source and resistance.

- The source applies a voltage V across a resistance R. This is the input. This results in current flowing through the circuit. Therefore, current is a response.

- According to the ohm's law,

V = I x R

V x (1/R) = I …................................(1)

- The equation (1) represents,

Input(V) x Transfer function(1/R) = Response(I)

- Therefore, the transfer function of the given electrical system is 1/R
