Hi guys. I'm completely new to electronics. I need a little help actually. I will keep it short.
Let's assume I'm having a battery of 9000mAh(11.42 V, 74.9 Whr) and a device rated as 5V, 55mA. My question is if I'm powering the 5V, 55mA device with that battery. How long will the battery last in hours assuming it had full charge? I would like to know the calculation steps for this. Thanks.
