🔍 Key Concepts

• How a DC voltmeter is connected in a circuit (in series or in parallel) • What happens to current flow when you add high resistance in series vs in parallel • The purpose of a shunt and where it is normally used (ammeter vs voltmeter)

💭 Think About

• Should a voltmeter take a lot of current from the circuit, or disturb the circuit as little as possible? • If you want to measure voltage across two points, should the meter path look like an easy path or a difficult path for current? • Which of the options is typically associated with ammeters rather than voltmeters?

✅ Before You Answer

• Recall that a voltmeter is connected across (in parallel with) the load, so it must have very high overall resistance • Think about whether shunts (low resistance paths) are used to bypass current around a meter movement — is that for voltage or current measurement? • Decide whether adding resistance in series or in parallel with the moving coil makes the meter draw less current for a given voltage
