1. What is Current in Parallel Branch?

The current in a parallel branch is the amount of electric current flowing through a specific branch of a parallel circuit. It can be calculated using Ohm's Law by dividing the voltage across the branch by the resistance of that branch.

2. How Does the Calculator Work?

The calculator uses the Ohm's Law equation for parallel branches:

Where:

• \( I_{branch} \) — Current in the branch (amperes)
• \( V \) — Voltage across the branch (volts)
• \( R_{branch} \) — Resistance of the branch (ohms)

Explanation: The current through each branch in a parallel circuit is independent of other branches and depends only on the voltage across it and its resistance.

3. Importance of Current Calculation

Details: Calculating branch currents is essential for circuit analysis, designing electrical systems, selecting appropriate wire gauges, and ensuring proper operation of electrical components.

4. Using the Calculator

Tips: Enter the voltage across the parallel branches (in volts) and the resistance of the specific branch (in ohms). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Is the voltage the same across all parallel branches?
A: Yes, in a parallel circuit, the voltage across each branch is the same as the source voltage.

Q2: How does current divide in parallel circuits?
A: Current divides inversely proportional to the resistance of each branch. Higher resistance branches get less current.

Q3: What happens if one branch has zero resistance?
A: This would create a short circuit with theoretically infinite current, which is dangerous and should be avoided.

Q4: Can I use this for AC circuits?
A: This calculator is for DC circuits. For AC, you would need to consider impedance rather than just resistance.

Q5: How does adding more parallel branches affect total current?
A: Adding more parallel branches decreases total resistance and increases total current drawn from the source.
