Extracted text: a) Wheatstone bridge as shown in Figure Q4(a) consists of four resistive arms forming a closed circuit with DC voltage source applied to two opposite junctions and a current detector connected to the other two junctions. R2 Voltage source Current R3 detector Rx Figure Q4(a) i) ii) State ONE (1) application for each AC and DC Wheatstone bridge. Formulate the equation for the unknown components, Rx at a balanced condition for DC bridge. b) Consider the AC bridge that has the configuration as shown in Figure Q4(b). i) ii) Indicate the bridge type and give its general equation at a balanced condition. Formulate the equation for the equivalent series resistance, Rx and inductance, Lx at a balanced condition. i) Compute the values of Rx and Lx when the bridge is in a balanced condition, given that, R1 = 1kO, C, = 1µF, R2 = 1000, R3 = 1000.
