Schering Bridge Question & Answers March 31, 2023 By Wat Electrical This article lists 50 Schering Bridge MCQs for engineering students. All the Schering Bridge Questions & Answers below include a hint and a link to the relevant topic wherever possible. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of the Schering Bridge. The Schering bridge is a type of AC bridge circuit used to measure the capacitance of a capacitor or to measure the dielectric constant of a material. There are three main types of Schering bridges they are balanced, unbalanced, and Wien bridges. The purpose of a balanced and unbalanced Schering bridge is to measure the capacitance of a capacitor. The Wien bridge is a type of Schering bridge that measures the dielectric constant of a material. The balanced Schering bridge balances the ratio of the four resistors and the unknown capacitance to cancel out the effects of the capacitance reactance and it produces a null output when the bridge is balanced. The balanced Schering bridge requires a sensitive detector or null indicator to measure the null output and it can be affected by stray capacitances or inductances in the circuit. The calibration of capacitors, quality control of capacitors, and measurement of low-loss capacitors, are the applications of a balanced Schering bridge. The unbalanced Schering bridge is a simpler circuit than the balanced Schering bridge and it can measure small capacitances. The capacitance meter and HP-4192A impedance analyzer are the applications of an unbalanced Schering bridge. The Wein bridge only works at high frequencies, and it can be affected by stray capacitances or inductances in the circuit. The measurement of the dielectric constant of materials is a disadvantage of the Wein bridge. 1). Which of the following bridges measures the capacitance of a capacitor?
