In electrical circuits, what do we use to divide voltage?

Resistors are used to divide voltage in electrical circuits through a concept known as a voltage divider. When resistors are arranged in series, the voltage across each resistor can be calculated based on the resistance values and the total voltage applied to the series circuit. According to Ohm’s Law, the voltage drop across a resistor is proportional to its resistance when connected in series with other resistors. This property allows us to create different voltage levels from a single source, making resistors an essential component in designing circuits that require specific voltage drops.

For example, if two resistors of equal value are connected in series across a voltage source, the voltage will be equally divided between the two resistors. This principle is widely used not only for power distribution but also in sensor circuits and audio applications, where it might be necessary to tap into a required voltage level.

While capacitors, inductors, and transformers play critical roles in electrical circuits, they serve different purposes. Capacitors are commonly used for energy storage and filtering, inductors are primarily involved in storing energy in a magnetic field and in filtering applications as well, and transformers change voltage levels using electromagnetic induction, rather than dividing voltage in a resistive manner. Each component serves its distinct function, emphasizing the unique ability
