In which configuration is current typically measured in a circuit?

Current is typically measured in series configuration within a circuit. When components are connected in series, the current flowing through each component is the same, making it an effective way to measure the current using an ammeter. An ammeter must be inserted into the circuit so that all current flowing through the circuit also flows through the ammeter. This ensures an accurate reading of the current, as the meter experiences the same current as the rest of the components in the series.

In contrast, if current were measured in parallel configurations, the flow would split among branches, complicated by the fact that an ammeter placed in such a position may lead to inaccurate readings due to different amounts of current flowing in different branches. Therefore, the series configuration is the preferred method for accurately measuring current in a circuit, providing a clear and consistent reading.
