When a resistor is used as a shunt and is connected in parallel with a meter movement coil, what capability does this provide?

🔍 Key Concepts

• Shunt resistor function in meter circuits • Effect of connecting components in parallel with a meter movement • How analog meters change range for larger currents

💭 Think About

• What happens to the total current path when you place a low-value resistor in parallel with a sensitive meter movement? • How do meters that can read both small and large currents usually achieve the higher current ranges? • Which of the choices describes a change in what the meter can handle rather than what it directly measures?

✅ Before You Answer

• Identify the primary purpose of a shunt resistor in measurement circuits (protecting the movement vs. measuring resistance vs. improving accuracy) • Consider which option matches a function commonly used in ammeter design • Eliminate any choice that contradicts standard meter construction practice (for example, saying it is never done).

Question 1 of 27070

When a resistor is used as a shunt and is connected in parallel with a meter movement coil, what capability does this provide?

a measurement of circuit resistance

an increased accuracy of approximately 1.5 percent

an extended meter range

this is never done
