2. Using the same current sensor as in (a), design a voltmeter with two scales: 0-10 V and 0- 100 V. What is the maximum current the instrument draws from the circuit for each scale? 3. Calculate the average value of the wave forms shown in Figure 1.2. Use (1). Assume that each division on the time axis corresponds to 1 s and each division on the y-axis corresponds to 1V. Also calculate the average value of 20cos(ot). x(t) (1) average X(t) (2) average Figure 1.2 For reference a) Design an ammeter with three scales: 0-200 µA, 0-2 mA, and 0-10 mA. Use a current sensor rated at 200 µA, 100 mV. What resistance does the instrument insert in the circuit at each scale? 2.
