1. What is a Parallel Circuit Current Calculator?

Definition: This calculator determines the total current in a parallel circuit by summing the currents through each branch.

Purpose: It helps electricians, engineers, and students analyze parallel circuits and ensure proper current distribution.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ I_{total} = I_{branch1} + I_{branch2} + I_{branch3} + \cdots \]

Where:

\( I_{total} \) — Total current (amps)
\( I_{branch} \) — Current through each parallel branch (amps)

Explanation: In a parallel circuit, the total current is the sum of all individual branch currents (Kirchhoff's Current Law).

3. Importance of Parallel Circuit Analysis

Details: Understanding current distribution helps in circuit design, component selection, and safety considerations.

4. Using the Calculator

Tips: Enter at least two branch currents (required) and optionally a third. All values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

Q1: Why does current add up in parallel circuits?
A: Current divides among parallel paths but the total equals the sum of all branch currents (Kirchhoff's Current Law).

Q2: What if I have more than three branches?
A: You can chain calculations by using the result as a branch current in another calculation.

Q3: Does this work for AC circuits?
A: Yes, but for AC you must consider phase angles (this calculator assumes all currents are in phase).

Q4: How do I measure branch currents?
A: Use an ammeter in series with each branch or calculate using Ohm's Law (I = V/R).

Q5: What's the relationship with voltage in parallel?
A: Voltage remains the same across all parallel branches while current divides.
