P1. Given the high-resistance Op-Amp-based Universal Voltmeter circuit below, Re-calculate the values of Ra, Rab, Ric, and Rid such that the meter movement ammeter with a full scale deflection of 50 A could be calibrated to read: a) 10Vdc, b) 10 Vrms (sinusoid), c) 10V peak (sinusoid), and d) 10V peak to peak (sinusoid). Then clearly explain how 7 points this voltage measurement device works in each case and justify the selection of your resistor values. [Hints: V = Varg = 0.636V peak, Vrms = 0.707 Vpeak] Ria = 100 Rib = 90 RIC rms = 63.6 km2 www Rid=31.8 k |dc da Function switch Op-p Peak 3 Du Da 741 D3 D Ips = 50 A -V E measured voltage
