## What are the types of AC bridges?

The various types of A.C Bridges are,

- Capacitance Comparison Bridge.
- Inductance Comparison Bridge.
- Maxwell’s Bridge.
- Hay’s Bridge.
- Anderson Bridge.
- Schering Bridge.
- Wien Bridge.

### What are AC bridges?

Definition: AC bridges are the circuits that are used for the measurement of electrical quantities such as inductance, capacitance, resistance. Along with these an ac bridge allows us to measure storage factor, loss factor, dissipation factor etc. AC bridges operate with only AC signal.

**How many types of AC bridges are classified?**

The AC bridges are classified into seven types. These are capacitance comparison bridge, inductance comparison bridge, Maxwell’s bridge, Hay’s bridge, Anderson Bridge, Schering bridge, Wein bridge.

**What is the principle of AC bridge?**

AC bridge circuits work on the same basic principle as DC bridge circuits: that a balanced ratio of impedances (rather than resistances) will result in a “balanced” condition as indicated by the null-detector device.

## How many AC bridges are there?

Following are the two AC bridges, which can be used to measure inductance.

### What is the difference between AC and DC bridge?

The main difference between AC and DC bridge circuits is that the AC bridge used to find the value of the unknown impedance of circuitry and DC bridge circuit is used to find the value of the unknown resistance of a circuit.

**Why is AC bridge used?**

Definition: The bridge uses for measuring the value of unknown resistance, inductance and capacitance, is known as the AC Bridge. The AC bridges are very convenient and give the accurate result of the measurement. The construction of the bridges is very simple.

**What is difference between AC and DC bridge networks?**

Difference Between AC & DC Bridge One of the significant difference between the AC and DC bridge is that the AC bridge is used for measuring the unknown impedance of the circuit whereas the DC bridge is used for measuring the unknown resistance of the circuit.

## Why we use capacitor in Anderson bridge?

Advantages of Andersons Bridge The fixed capacitor is used, whereas other bridges use a variable capacitor. The bridge is used for accurate determination of inductance in the millimeter range. This bridge also gives an accurate result for the determination of capacitance in terms of inductance.
