Questions: A circuit that is ground-switched is connected to ground: Only when the load is connected to positive. Only when the load is being commanded on. All the time.

Solution Steps

A ground-switched circuit is a type of electrical circuit where the switching mechanism is on the ground side of the load. This means that the load is connected to the positive voltage supply all the time, and the circuit is completed by connecting the ground when the load is to be activated.

• Option 1: Only when the load is connected to positive.
  This is incorrect because the load is typically always connected to the positive side in a ground-switched circuit.

• Option 2: Only when the load is being commanded on.
  This is correct because the ground connection is made only when the load is supposed to be turned on, completing the circuit and allowing current to flow.

• Option 3: All the time.
  This is incorrect because the ground connection is not made all the time; it is only made when the load is commanded to be on.
