Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed.. Ohm''s law tells us the relation between current, voltage, and resistance: I = V / R (current = voltage / resistance) Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term for resistance) the device places on the …

Contact UsHow does the resistor limit the current across the circuit when …
Electricity is pretty similar. Electrically, pressure is ''voltage'' and flow is ''current'' - just like the current in a river (which is where the term comes from). Current is the number of electrons per second, if you will, that go through the hose (or ''circuit''). SO, for a given pressure, with less resistance there is more current.
