I need to find the type of Resistor I need so I know the Formula is E over I = R but I need some help.
My Current is 20mA and my Voltage is 4000mV and yes I know you first write 20mA as .020 Amp.
Now I know 4000mV is in one Volt.
But would I not write 4000mV as .0004 Volts?
Then do the E over I to get my R in Homs?
You see my Amps are 20mA so I write it as .020 so I thought I would do the same with my 4000mV I would write it as .0004 Volts?
