Voltage Division Method

In the electronics branch, a voltage divider is required to produce a section of its input voltage as an output. This basic circuit may be prepared with two resistors or any passive elements along with the voltage source. The circuit resistors are attached in series and a voltage source is braced across these resistors. The input voltage can be transferred between the resistors in the circuit for the voltage division to occur. The SI unit of electrical resistance is ohm (Ω) or kilo-ohms (kΩ).
