The ac bridge of Figure 48 nulls with R L3 = 250 mH. a. Find the values of R4 and L4. b. If the circuit is excited by a 5-V rms, 1-kHz oscillator, find the offset voltage for L4 = 510 mH. c. What are the amplitudes of the in-phase and quadrature (90) components of the offset voltage? = 1 , R2 = 2 , R3 = 100 , and FIGURE 48 ac bridge for Problem 14. R 13 D
