WebAmmeters measure current in two metrics - ‘draw’, the flow of current in a particular circuit, and ‘continuity’, the steadiness of the current and the presence or absence of interruptions. Ammeters are used to detect problems in electrical circuits - unusually high or low levels of current, for example. The former can indicate ... WebUsing an ohmmeter, check the drain to source resistance of the MOSFET. You should expect a very low value reading on the ohmmeter, which tends to zero in this step. If you obtain such a reading, the MOSFET is in good condition. Next, you need to check the MOSFET’s datasheet to confirm the drain to source resistance when the device is on.
