1. Design an ammeter with three scales: 0-200 EA, 0-2 mA, and 0-10 mA. Use a current sensor rated at 200 EA, 100 mv.

 

1. Design an ammeter with three scales: 0-200 EA, 0-2 mA, and 0-10 mA. Use a current sensor rated at 200 EA, 100 mv. What resistance does the instrument insert in the circuit at each scale? 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 eachscale?
