As the name suggests, voltage divider, the circuit that divides the input voltage into the required levels. A voltage divider is a general term, one can use a potentiometer for voltage division, but the type we will restrict ourselves in this post is resistors based voltage division.
Voltage divider the two resistor voltage divider is used often to supply a voltage different from that of an available battery or power supply. In application the output voltage depends upon the resistance of the load it drives.

A problem seen at high frequencies is that stray (parasitic) capacitance effects with the overall response of a resistive voltage divider. The simplest way to correct for this problem is to introduce capacitors in parallel to the resistors.

A voltage divider circuit or a potential divider circuit is a simple electronics circuit that converts a higher input voltage to a lower output voltage just by using a couple of resistors. It is often used in analog circuits like op-amp based circuits for example, where the required voltage may be variable.

For high-power applications, reactive voltage dividers are preferred since they do not dissipate to much power by joule’s heating. Alternative voltage dividers can be based on a capacitor or inductor instead of a resistor, they are known as reactive voltage dividers.
A voltage divider circuit is a very common circuit that takes a higher voltage and converts it to a lower one by using a pair of resistors. The formula for calculating the output voltage is based on ohms law and is shown below.
The resistors are made of an electrically resistive film material and each resistor is applied as a trace onto an insulating substrate.
It's output voltage is a fixed fraction of its input voltage.
It is materialized by arranging an ohmic resistor r3 in connection with a co-axial cable in the input line to the measuring instrument.
This value agrees with the characterization of ac–dc difference using thermal converters from different producers with a variety of resistance for various voltages.
Standard (jvs) has the required uncertainty for the measurements but the output resistance of these dividers is high enough (40 kohm).
In many cases you'll find that the input current is so high that a voltage divider by itself isn't going to work. For those circuits you might use a divider feeding an op-amp set up as a unity gain buffer. That way the resistors can be fairly high values and not be affected by the input current of the rest of the circuit.
