(a) The two ends of each resistor are connected together. The circuit characteristics are derived from Kirchhoff's law: The figure shows the parallel connection of n resistors, and the voltage and current reference directions are related. The power consumed by the equivalent resistance is equal to the sum of the power consumed by each series resistor.įigure4.When resistors are connected in series, the power consumed by each resistor is proportional to the size of the resistor, that is, the larger the resistance, the larger the power consumed. Solution: From the partial pressure formula of series resistance:ĭraw conclusions from the above formulas: Therefore, the series circuit can be used as a voltage divider circuit.Įxample 1: Calculate the voltage across the two series resistors as shown in the figure. The higher the resistance value, the higher the voltage. Resistors are connected in series, and the voltage on each sub-resistor is proportional to the resistance value. If the total voltage across the series resistor is known, what is the divided voltage on each resistor?
