How should probes be connected when measuring amperage on a powered circuit?

To measure amperage on a powered circuit correctly, the probes must be connected in series with the circuit. This method allows the current to flow through the measuring device, enabling it to accurately gauge the amount of current passing through the circuit. When the probes are placed in series, all the current flowing through the circuit also flows through the ammeter (or other measuring device), which yields the correct measurement of amperage.

Connecting probes in parallel, as suggested in one of the options, would result in a short circuit, as it would create an alternate path for the current, effectively bypassing the load. This could potentially damage the measuring device and create a safety hazard. Similarly, connecting probes directly across a load would measure voltage, not current, and would not provide any information about the amperage in the circuit. Lastly, only connecting to grounded components could lead to inaccurate readings and does not serve the purpose of measuring current. Thus, connecting the probes in series is the correct and safe method for measuring current in a powered circuit.
