Concept:A milli-ammeter measures only small currents.
To convert it into an ammeter, a low resistance called a shunt must be connected in parallel with it.
This shunt allows most of the current to bypass the meter.
Explanation:An ammeter is designed to measure large currents without being damaged.
When a low-resistance wire or resistor is placed in parallel with a milli-ammeter, the total current splits.
The meter carries only a small safe portion, while the shunt carries the remaining large current.
Connecting a low resistance in series would increase the circuit resistance and reduce the current, so it is not suitable.
A high resistance, whether in series or parallel, would not properly divert the current and would affect the reading.
Therefore, the correct conversion requires a low-value resistor connected in parallel.
Answer:C. low value in parallel with it
