Homework Answers
Yes, GPIO have maximum rating of upto 100mA. means it can give maximum of 50mA current to it's connected line(pin).
In your case total resitance of line is 50ohm + 50ohm = 100ohm, which takes more than 30mA from the GPIO pin, which may result in damage the GPIO.
I = V / R
= 1.5 / 100
= 0.015A
which is lesser than 100mA ------(VDDSHV6)
different GPIO of the can provide different voltage level due multifunctional operation of pin. you need to check the particular GPIO pin for the task. although processor maximum voltage output voltage can be 5 volts for specific pin (example - USB PIN) and if you connect 100 ohm in this pin than current withdrawn is 50mA which is the maximum current provided by GPIO0_6 and many other.
you can datasheet for different GPIO maximum current rating.
