To safely measure current with a DC milliammeter, how is the meter connected?

Question 1 of 27070

To safely measure current with a DC milliammeter, how is the meter connected?

🔍 Key Concepts

• How ammeters are placed in a circuit to measure the current through a load • Difference between measuring current and measuring voltage • Why polarity matters in a DC (direct current) circuit

💭 Think About

• Think about where the current must flow so that the meter shows the same current that is flowing through the load. • Ask yourself: when you measure voltage, how do you connect a meter, and how is that different from measuring current? • Consider what could happen to the meter or circuit if you connected it the wrong way.

✅ Before You Answer

• Verify whether an ammeter is designed for series or parallel connection. • Check if a DC meter movement can be connected without regard to polarity, or if reversing leads would affect it. • Consider why an answer mentioning internal shunts only does or does not describe how you connect the meter in the circuit.
