Question

What is the main use of a voltage divider in microprocessor applications? Explain your answer with a schematic. 7. Suppose a DC power source with a voltage of 50 volts is connected to a 10 Q load. How much power will this load dissipate? Now suppose the same 10 H load is connected to a sinusoidal AC power source with a peak voltage of 50 volts. Will the load dissipate the same amount of power, more power, or less power? Explain your answer. 8. An inductor rated at 4 Henrys is subjected to a sinusoidal AC voltage of 24 volts RMS, at a frequency of 60 hertz. a) Write the formula for calculating inductive reactance (Xl), and solve for current through the inductor. b) Calculate the impedance of this inductor circuit in polar form. 9. For an A/D converter with Vref = 5 V, what is the voltage resolution if the converter is of 8 bits? 10 bits? 16 bits? 24 bits?

Explanation / Answer

voltage is really easy for microcontrollers (those with analog-to-digital converters - ADC
