1. What is Voltage Across Resistor in Parallel?

Definition: This calculator determines the voltage across a resistor in a parallel circuit configuration.

Purpose: It helps electrical engineers, technicians, and students understand and verify voltage distribution in parallel circuits.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Voltage across resistor (volts)
• \( V_{source} \) — Source voltage (volts)

Explanation: In a parallel circuit, the voltage across each component is equal to the source voltage.

3. Importance of Voltage Calculation

Details: Understanding voltage distribution is crucial for circuit design, troubleshooting, and ensuring components receive proper operating voltage.

4. Using the Calculator

Tips: Simply enter the source voltage in volts. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is voltage the same across parallel components?
A: In parallel circuits, all components are connected directly to the same voltage source points.

Q2: Does this apply to all parallel circuits?
A: Yes, this is a fundamental characteristic of parallel circuits, regardless of the number or type of components.

Q3: How does this differ from series circuits?
A: In series circuits, voltage divides among components, while in parallel, voltage remains constant across all components.

Q4: What about current in parallel circuits?
A: Current divides in parallel circuits, unlike voltage which remains constant.

Q5: Does resistor value affect the voltage in parallel?
A: No, the voltage remains the same regardless of resistor value, though current through each resistor will vary.
