Answer:
effort force: The force used to move an object over a distance. resistance force: The force which an effort force must overcome in order to do work on an object via a simple machine. ideal mechanical advantage: The factor by which a mechanism multiplies the force put into it.

Answer:
The switch within the closed circuit is opened and it stops the flow of current in a circuit.
Explanation:
- Current is defined as a flow of electrons in a system or a circuit.
- There are two basic things needed for current to flow in a system
- One is the electro-motive force and the other is the complete path for current to flow.
- If a switch in a closed circuit gets opened, it restricts the path of current flow.
- Thus it stops the current to be flowed through the circuit.
