FEATURES
  • A designed according to the principle of ohms law and through the resistor in parallel through a different switch, can produce 3 kinds of 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 ohms law: I = U/R
  • Resistor in parallel calculation formula: R=1/(1/R1+1/R2+…+1/Rn) K1=4.7Ohm/10W , K2=2.2Ohm/10W
