| The current through the resistor is the voltage read on channel 1 divided to it's resistance value. Because the resistor used is 1kΩ, the numeric value of the current is the same as the voltage but in micro amperes. | The current through the resistor is the voltage read on channel 1 divided to it's resistance value.
