Hi i try to measure the resistance of a fan using a ohm rule i connected the ground of the fan to a 3 volt(2 battaries) and the possitive to a measurement device and the other leg of the measurement device to the possitive of the fan i got some result and calculated the resistance but when i increased the volt and used ohm low to calculate the i , and measured the i i got different i in practice then in the calculation
can someone explain? thanks
