How the Calculator Works

The Combination Circuit Calculator uses basic electrical principles to compute total resistance and current:

• Series Circuits: Total resistance is the sum of all resistors. Rtotal=R1+R2+R3R_{total} = R_1 + R_2 + R_3Rtotal​=R1​+R2​+R3​
• Parallel Circuits: Total resistance is calculated using the reciprocal formula: Rtotal=11R1+1R2+1R3R_{total} = \frac{1}{\frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3}}Rtotal​=R1​1​+R2​1​+R3​1​1​
• Current Calculation: Once total resistance is determined, total current is calculated using Ohm’s Law: Itotal=VRtotalI_{total} = \frac{V}{R_{total}}Itotal​=Rtotal​V​

By entering resistor values and voltage, the calculator provides instant results for any circuit configuration.

Practical Example

Imagine a circuit with three resistors and a voltage source:

• Resistor R1: 100 Ω
• Resistor R2: 200 Ω
• Resistor R3: 300 Ω
• Voltage: 12 V

Series Circuit Calculation:

• Total Resistance = 100 + 200 + 300 = 600 Ω
• Total Current = 12 ÷ 600 = 0.02 A

Parallel Circuit Calculation:

• Total Resistance = 1 ÷ (1/100 + 1/200 + 1/300) ≈ 54.55 Ω
• Total Current = 12 ÷ 54.55 ≈ 0.22 A

With the calculator, these results appear instantly, making it easy to compare configurations and understand circuit behavior.
