Hi all. I am newbie to electronics and this forum.
I am trying to get my head round ohm's law ( V = IR ).
I got 2V power supply with current set to 0.04 A. I connected both ends power supply to a resistor of 470 Ohms. Now when I connect multimeter (set to volt), to the ends of resistor I get reading of 2.0 Volts.
From Wiki :
"A resistor is a twoterminal electronic component that produces a voltage across its terminals that is proportional to the electric current through it in accordance with Ohm's law"
so how come I get 2 volts ?
Any help will be appreciated
Thanks
Kazz
