What is meant by C-rate and how to calculate current from it?
The Amp-hour rating of a battery is the rating that tell you what level of current a battery can theoretically supply before dying. So if a battery is rated for 60 Amp-hours, it means that the battery should be able to supply: 60 Amps for one hour (C-rate = 1) 120 Amps for half an hour (C-rate = 2) 30 Amps for two hours (C-rate = 0.5)

How do you calculate a voltage / current / resistance?
V is the symbol for voltage. I is the symbol for current. R is the symbol for resistance. I use it VERY often. It is THE formula in electronics. You can switch it around and get R = V/I or I = V/R. As long as you have two of the variables, you can calculate the last. Electronics is easy when you know what to focus on and what to ignore.
What happens if a battery carries a current?
