When an ohmmeter is connected across a large, discharged capacitor, the reading typically shows increasing resistance with time. This behavior can be understood by considering the nature of capacitors and how they interact with the ohmmeter.

Initially, when the ohmmeter is connected, it applies a small voltage across the capacitor plates. Since the capacitor is discharged, it initially presents a low resistance. However, as the capacitor charges up from the current supplied by the ohmmeter, the current flow decreases. The capacitor starts to accumulate charge, which causes the resistance reading to rise over time. This increasing resistance indicates that the capacitor is charging, which is consistent with the behavior of a discharged capacitor being connected to a circuit.

The other options do not accurately reflect what happens with a large, discharged capacitor. A decreasing resistance would suggest that the capacitor is shorted, which is not the case. A steady full-scale reading might imply that there is an open circuit or that the capacitor is fully charged, neither of which accurately describes a discharged capacitor. Alternating between open and short circuit is also not typical for this scenario, as it indicates erratic behavior rather than the expected gradual charging of the capacitor.
