🔍 Key Concepts

• Ammeter measures current and is placed in series in a circuit • Shunt resistor provides an alternate path for current around the meter movement • Relationship between current, resistance, and meter range (Ohm’s Law)

💭 Think About

• If a sensitive ammeter movement can only handle a small current, what must happen to the extra current when measuring a much larger current? • Does placing a low‑value resistor in parallel with the ammeter cause more or less current to bypass the meter movement? • How would bypassing current affect the maximum current the ammeter can measure without damage?

✅ Before You Answer

• Remember that a shunt resistor is usually low resistance and connected in parallel with the ammeter movement • Think about whether bypassing some current allows the meter to handle higher or lower total current in the circuit • Check which choice correctly connects a shunt with changing the current range of an ammeter, not a voltmeter
