The current through an initially uncharged 4uF capacitor is as attached. Find the voltage across the capacitor for 0<t<3. I have following calculation: i = 40mA 0 <t < 1 i = 0 1 < t < 2 i = -40mA 2 < t < 3 since the voltage across capacitor is given by: v = (1/c) ∫ i dt + v(t0)...

Thanks for input The operating frequency is between 10KHz to 100kHz, recommended is 20KHz. So I chose the values closest to 52% duty cycle. I checked with RA = 40.2K and RB = 360K and it failed at 70% RH. To keep accurate RH calculation I chose these resistors in the range of 0.05% so I have...

Hi I am currently using LCM555 timer for generating variable frequency based on relative Humidity (RH) of surrounding. The LCM555 is configured as astable multivibrator and centered at 20KHz. RA = 24K, RB = 200K and C is capacitive sensor having value of 160pF at 30C, 0%RH. The C is given by...
