Question

Observe the simple circuit in the diagram (Figure 1). The component labeled "DC Amps" is an ammeter, and the one next to it is a light bulb. Fill in the blank: Figure 1 is a diagram of a ________ circuit. short closed (but not short) open complex (combining series and parallel) If one additional wire is connected to this circuit, as shown in Figure 2, the current measured by the Ammeter will increase decrease stay the same stop flowing Predict what would happen to this simple circuit if an additional wire were added to the circuit shown in Figure 1 so as to connect the terminals of the battery as shown in Figure 3. The current measured by the Ammeter will slightly increase slightly decrease stay the same virtually stop flowing

Explanation / Answer

1] This is a normal closed circuit where all the components are connected to each other (not an open circuit).

2] The Ammeter will measure the current drawn from the circuit so if another wire is put between the ammeter and the bulb, the Ammeter current will be the same.

3] If a wire is connected across the battery directly, then the current will chose this path since this offers the least resistance. Therefore, the current at the ammeter will drop to zero meaning the current in the ammeter will virtually stop flowing.
