12 Best Free Online Wheatstone Bridge Calculator Websites

Here is a list of the best free online Wheatstone Bridge Calculator websites. A Wheatstone Bridge is an electrical circuit used to measure an unknown electrical resistance. It is a rhombus-shaped network of four resistance arms connected to an external voltage source. It relies on the principle that when the bridge is balanced, the ratio of resistances in one leg is equal to the ratio in the other leg. You can add an unknown resistance along with 3 known resistances into the bridge and measure the input and voltage. Then you can simply use the Wheatstone Bridge formula to find the value of the unknown resistance.

An online Wheatstone Bridge calculator can help you quickly and accurately perform this calculation. In this post, I’m covering 12 websites that offer Wheatstone Bridge calculators online. Most of these calculators are capable of finding the unknown resistance and voltage. Whereas a few are specific to either unknown resistance or the voltage. I briefly covered each calculator along with the calculation steps. I also mentioned the highlights of each calculator that can help you quickly grasp the capability of that calculator. You can go through the post to check these out in detail.

Frequently Asked Questions

What is Wheatstone Bridge?

A Wheatstone Bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit. It relies on the principle that when the bridge is balanced, the ratio of resistances in one leg is equal to the ratio in the other leg, allowing for precise resistance measurements.

How do you calculate Wheatstone bridge?

To calculate an unknown resistance (R_x) in a Wheatstone Bridge, use the formula: R_x = (R2 * R3) / R1, where R1, R2, and R3 are the known resistances in the bridge circuit. Ensure the bridge is balanced (no current flows through the galvanometer) for an accurate measurement.

How do you solve a Wheatstone bridge problem?

To solve a Wheatstone Bridge problem: 1. Use the formula R_x = (R2 * R3) / R1 to calculate the unknown resistance R_x. 2. Ensure the bridge is balanced by adjusting a variable resistor (if available) until the galvanometer shows no current flow for an accurate result.

What is the value of the Wheatstone bridge?

The value of a Wheatstone bridge lies in its precision and versatility for measuring unknown electrical resistances, making it a fundamental tool in electrical engineering and metrology. It provides a reliable means to determine resistance values by achieving a balanced state in the circuit.

What is the balance voltage of the Wheatstone bridge?

The balance voltage of a Wheatstone bridge is the voltage across the galvanometer when the bridge circuit is in a balanced state, which means no current flows through the galvanometer. It indicates that the ratio of resistances in one leg of the bridge is equal to the ratio in the other leg.

Is Wheatstone bridge AC or DC?

Wheatstone's bridge is a simple DC bridge, which is mainly having four arms.

What is the range of Wheatstone?

Wheatstone bridge is used to measure medium resistances in the range of 1Ω to a few megaohms.

Why Wheatstone bridge is called so?

The Wheatstone Bridge is named after its inventor, Samuel Hunter Christie, who developed the concept in the early 19th century. Sir Charles Wheatstone, a British scientist, popularized and refined the bridge circuit, leading to its widespread use in electrical measurements, and thus, it came to be known as the "Wheatstone Bridge."
