State three detectors used in ac Bridge?

1. Capacitance detector: This detector measures the capacitance of the unknown component in an AC bridge circuit. It typically consists of a variable capacitor and a galvanometer.

2. Inductance detector: This detector measures the inductance of the unknown component in an AC bridge circuit. It usually includes a variable inductor and a galvanometer.

3. Resistance detector: This detector measures the resistance of the unknown component in an AC bridge circuit. It typically consists of a variable resistor and a galvanometer.
