If a proper Power rating is not selected the resistor will overheat and might also burn. By putting the values of Input voltage and R1 and R2 in this equation, we get. How it works is, the ratio of the resistors (R1 and R2) divides the input voltage down to a lower output voltage. We can utilize this voltage divider rule to broaden the circuits, intended to use multiple resistors as well. Voltage divider calculator It is used to calculate the voltage drops on the individual resistor load when it is connected in a sequence. inefficient, enough current running through R1 would likely cause the resistor to burn up. In their simplest form, capacitors consist of two conducting plates separated by an insulating material called the dielectric. Another area where voltage dividers are useful is when a voltage needs to be leveled down. This equation shows the voltage divided between the two resistors, which are directly proportional to their resistance.
