Identify the correct statement regarding the placement of an ammeter to measure the current through a resistor R in a simple circuit.
(a) It must be connected in parallel with R so that the full battery voltage appears across the ammeter
(b) It must be connected in series with R but through a large resistance shunt to avoid affecting the circuit current
(c) It must be connected in series with R so that the same current flows through both
(d) It should be connected in parallel with R for large currents and in series only for very small currents
