Hi all,
I recently bought a 0.5ohms 5watt resistor for my over current protection circuit . As per the calculations , the resistor must provide a voltage drop of 0.5v when 1A of current flows through it
But when I measure it with my multi meter, it reads 0.05v. This becomes 0.1v for 2A. I even measured the readings with another multimeter to make sure that nothing is wrong with my meter and I got the same reading .
Please help me to solve this problem .
