Source transformation - Voltage Source to Current Source or Current Source to Voltage Source

An electrical source transformation is a method for simplifying circuits by replacing a voltage source with its equivalent current source, or vice versa.

Source transformation - Voltage Source to Current Source or Current Source to Voltage Source

According to the Thévenin and Norton theorems, any linear voltage source can also be viewed as a linear current source. Which circuit you use depends on which ideal form describes the behavior of your circuit in more detail.

Voltage source    <=>    current source

U_out = U_s – I * R_s        <=>     I_Rout = I_S – U_out / R_s
where R_s = U_s / I_max and I_s = V_s / R_s
