Voltage Divider Rule

The Voltage Divider Rule is a way to determine how voltage is distributed across components in a series circuit. When resistors are connected end-to-end, the total voltage supplied by the power source divides among them based on their resistance. The higher the resistance of a component, the more voltage it will drop across it. This rule allows you to calculate the voltage at any point in a series circuit using the ratio of the resistor’s resistance to the total resistance. Essentially, it helps predict how voltage is shared among series-connected devices.
