Parallel Circuit Calculator
Calculate total resistance, current, voltage, and power in parallel circuits. Perfect for electronics hobbyists, students, and engineers designing circuits.
Step 1: Circuit Specifications
12 V
Parallel Circuit Formula
Total Resistance: 1/Rtotal = 1/R1 + 1/R2 + … Voltage is same across all branches. Current divides inversely with resistance.
Step 2: Advanced Settings
1 A
Important Notes
Total parallel resistance is always less than the smallest resistor. Ensure power ratings are not exceeded. Current through each branch = Voltage / Resistance.
