hi, as part of a project me and my friends are undertaking we are trying to measure the change in resistance of an electromagnet when a coin is placed near near the electromagnet. i have been trying to use a bridge rectifier to convert the system to DC but i have been encountering a few problems,
the voltage across the bridge circuit seems to be charging to -15V and does the same even if i change the direction of the capacitor in the bridge rectifier
if anyone could shed any light onto why this is happening or knows how to help then it would be greatly appreciated
many thanks
