Smaller load resistances lower the voltage and increase the current, so the smallest current corresponds to the largest voltage.
A voltage-divider is a simple circuit that is used to divide a voltage into smaller parts. It consists of two resistors in series, with the output voltage taken from the connection between the two resistors.
A voltage-divider works by using the concept of voltage division, where the total voltage across a series circuit is distributed among the different components based on their resistance values. In a voltage-divider, the output voltage is proportional to the ratio of the two resistors used.
A voltage-divider is commonly used in electronic circuits to provide a specific voltage level for different components, such as sensors, transistors, and microcontrollers. It is also used in power supplies to regulate the output voltage and in audio circuits to adjust the volume level.
To design a voltage-divider, you will need to know the desired output voltage and the input voltage. Using Ohm's law, you can calculate the resistance values for the two resistors needed to achieve the desired output voltage. The formula for a voltage-divider is Vout = Vin * (R2 / (R1 + R2)).
When designing a voltage-divider, it is important to consider the power rating of the resistors used, as well as their tolerance and temperature coefficients. It is also essential to make sure the output voltage does not exceed the maximum rating of any components connected to the circuit. Additionally, the values of the resistors should be chosen to minimize the effect of any input or output impedance on the circuit's performance.
