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 in an ammeter should be connected in parallel with the meter movement, not the load. This allows the ammeter to measure the current by diverting a portion of the current through the shunt, which has a lower resistance than the meter movement. Connecting the shunt in series with the load would create an additional resistance in the circuit, which is not the desired arrangement for an ammeter.
The other options are incorrect because A) has the shunt in series with both the load and the meter movement, B) has the shunt in parallel with the load which is not the correct configuration, and D) has the shunt in parallel with both the load and the meter movement, which is also not the correct setup for an ammeter.
