A voltage divider is a simple circuit which turns a large voltage into a smaller one. Using just two series resistors and an input voltage, we can create an output voltage that is a fraction of the input. Voltage dividers are one of the most fundamental circuits in electronics.
What is a variable voltage divider?
In electronics, a voltage divider (also known as a potential divider) is a passive linear circuit that produces an output voltage (Vout) that is a fraction of its input voltage (Vin). Voltage division is the result of distributing the input voltage among the components of the divider.
Is a parallel circuit a voltage divider?
In a series circuit ,the voltage across the circuit is the sum of the voltages across each component. In a parallel circuit, the voltage across each of the components is the same. (R1+R2)//(R3+R4) , therefore voltage across R1+ R2 are same as R3+R4, find this voltage V, then use voltage divider rule again .
