In a circuit with an open switch, the current will ?.

Explanation:
Current requires a closed path for charges to move. When the switch is open, the circuit is broken, so there is no complete loop for electrons to travel from the source through the load and back. In this situation the current is effectively zero (I = V/R, with the open break making the resistance effectively infinite). Only minuscule leakage currents, if any, might occur in real components, but in ideal analysis there is none. So the current does not flow.
