Answer
Any of these circuits
Explanation
## Step 1:To determine the current flowing through a lamp, the student needs to set up a circuit that allows for the measurement of current. The circuit should include a power source, the lamp (which acts as the load), and an ammeter (a device used to measure current).## Step 2:Without specific details about the circuits labeled A, B, C, and D, we cannot determine which circuit is appropriate based solely on the labels. However, the correct circuit would be the one that connects the ammeter in series with the lamp. This is because current must flow through the ammeter for it to be measured.## Step 3:The student should ensure that the ammeter has an appropriate range for the expected current and that the circuit is connected properly to avoid any short circuits or damage to the ammeter.
