What is a voltage divider circuit
A voltage divider network is a fundamental electronic circuit used to divide a voltage into smaller fractions. It consists of two or more resistors connected in series or in a string, which create intermediate voltage points between the supply voltage and ground. Voltage dividers are commonly used for various purposes in electronics, including setting reference…
