30)This multiple choice question from MEASUREMENTS INSTRUMENTATIONS course.

Voltage Zener is used in the circuit below and the load current is to vary from 12 to 100 mA. Find the value of series resistance R and the range of load resistance to maintain a voltage of 7.2 V across the load. The input voltage is constant at 12V and the minimum Zener current is 10 mA. ... IL R Iz Eo RL Vz E, = 12 V

Hi i am trying to convert a pwm signal to a ramp signal, i have an output that currently generates around 26mA but I want a ramp current signal that will range between 0 -100mA depending on the duty cycle of the PWM . so this means that the circuit should include an amplificator to get the current to 100mA. can you please draw the circuit thank you
