Question 82Electricity/Electronics - 1st Asst/Chief70% to pass
How should the shunt used in an ammeter be connected?
AI Explanation
The correct answer is C) in series with the load and in parallel with the meter movement.
The shunt used in an ammeter should be connected in series with the load and in parallel with the meter movement. This is because the ammeter needs to measure the current flowing through the load, so the shunt must be connected in series with the load to allow the full current to pass through. However, to prevent the ammeter from drawing too much current and potentially damaging the meter movement, the shunt is connected in parallel with the meter movement, allowing only a small portion of the current to pass through the meter.
The other options are incorrect because: A) the shunt should not be in parallel with the load, as that would bypass the current measurement; B) the shunt should not be in series with the meter movement, as that would not allow the meter to function properly; and D) the shunt should not be in parallel with both the load and the meter movement, as that would not provide the necessary current measurement.
