Series and Parallel Circuit Calculation Formula
The following formulas are used to calculate the current and total resistance in series and parallel circuits.
Series Circuit: I = V / R
Parallel Circuit: 1/R_total = 1/R1 + 1/R2 + ... + 1/Rn
Variables:
- I is the current (Amps)
- V is the voltage (Volts)
- R is the resistance (Ohms)
- R_total is the total resistance in a parallel circuit (Ohms)
To calculate the current in a series circuit, divide the voltage by the resistance. For a parallel circuit, calculate the reciprocal of the sum of the reciprocals of each individual resistance to find the total resistance.
What is Series and Parallel Circuit Calculation?
Series and parallel circuit calculation involves determining the electrical properties of circuits with components connected in series or parallel. In a series circuit, components are connected end-to-end, resulting in the same current flowing through all components but different voltage drops. In a parallel circuit, components are connected across the same voltage source, resulting in the same voltage across all components but different currents.
How to Calculate Series and Parallel Circuits?
The following steps outline how to calculate the current and total resistance in series and parallel circuits using the given formulas.
- For series circuits, determine the total resistance by summing up all resistances.
- Next, use Ohm’s law (I = V / R) to calculate the current.
- For parallel circuits, calculate the reciprocal of the total resistance using the reciprocals of individual resistances.
- Use the total resistance and voltage to find the total current using Ohm’s law.
