FAQ on voltage and current sources, Part 2

October 9, 2024 By Bill Schweber

Voltage and the lesser-known current sources provide important IC, circuit, and system functions. Current sources We have examined voltage sources, and now we can examine their less-known but necessary complement, the current source. Q: What is a current source? A: As the name implies, the current source is like a voltage source but different. It […]

How fast can Li-on batteries be charged?

June 13, 2022 By Jeff Shepard

The speed at which a battery can be recharged is measured using the ‘C-rate,’ where ‘C’ is the battery’s capacity in mA or A. At a 1 C rate, a battery can be completely recharged in one hour. The speed of charge primarily depends on the voltage. For example: For small batteries used in portable…
