I'm pretty new to all this. Please forgive me if this is an obvious question.
I am working with an ESP8266 module. They generally have a max operating current draw of somewhere around 250 mA. I have noticed that under certain conditions it can seize up, and starts drawing current at an unusually high rate.
I am operating this off a steady 3.3v DC supply, so I was thinking of using a resistor to limit the current going into the module when this happens, but would like for someone to double check my math here.
At 3.3v a 10 ohm resistor should cap me well within my safe range at 330 mA, correct? Going further with the math, 330 mA at 3.3v would be just over a watt of power. So would I need a resistor rated for over a Watt?
