To measure current through a component, the ammeter must be connected __________ the component.

To measure current through a component, the ammeter must be connected in series with that component. When an ammeter is placed in series, it becomes part of the circuit, allowing the entire current flowing through the component to pass through the ammeter. This setup enables the ammeter to accurately measure the amount of electrical current flowing at any moment.

If an ammeter were connected in parallel, it could cause a short circuit, as ammeters are designed to have very low resistance. This would not only lead to inaccurate measurements but could also damage the ammeter or the circuit. Connecting an ammeter "across" or "along" the component would not allow for the measurement of current either, as these configurations do not integrate the ammeter into the direct path of the current flow through the component. Thus, connecting the ammeter in series is the correct approach to accurately measure current in a circuit.
