Q

When measuring DC current flow using an analog or digital multimeter set up as a milliammeter, how is the meter connected?

🔍 Key Concepts

• How ammeters are connected in a circuit (compared to voltmeters) • Effect on the circuit if you bypass the load versus go through the load • Difference between series and parallel connections in basic DC circuits

💭 Think About

• Think about what the meter is trying to measure: is it measuring the push (voltage) across a component or the flow (current) through it? How does that affect where you place it? • If you connected the meter so that current could go around the load instead of through it, what would that do to the circuit and the reading? • In a simple battery-lamp circuit, sketch where you would break the circuit to insert a milliammeter so all current must pass through it.

✅ Before You Answer

• Be clear on the difference: voltmeters are connected one way, ammeters another way • Ask: does the meter need to see all the current flowing to the load, or just the voltage difference across the load? • Ensure the connection method does not short-circuit the power source around the load.
