Following is a list of bridges used in measurement of resistance, capacitance, and inductance: For resistance –

• Wheatstone’s Bridge – Galvanometer pointer deflects as per changes in current

• Kelvin’s Bridge – Modified version of Wheatstone’s Bridge, particularly used for very low resistance measurement

For capacitance –

• Schering Bridge – Comparison of capacitances

• Wien’s Bridge – Precision measurement of capacitance in terms of resistance and frequency

• De Sauty’s Bridge – Standard comparison of capacitances

For inductance –

• Maxwell Bridge – Used to find out the self-inductance and the quality factor of the circuit

• Hay’s Bridge – Modified version of Maxwell Bridge
