ATORCH USB resistor DC electronic 5V 1A/2A/3A load With switch adjustable 3kind current voltage discharge tester
A designed according to the principle of ohm's law and through the resistor in parallel through a different switch, can produce3 kindsof resistance of a new USB electronic load resistance discharge, when all the switch opens, is 2.2 ohm/10W, 4.7 ohm/10W, 2 kinds of resistance in parallel at the same time, in 5V voltage almost can produce 3A discharge current.
The actual current size, please according to ohm's law:I = U/R
