A current reading is obtained by properly placing an ammeter in a circuit consisting of one resistor and one battery. As a result,
A)the voltage drop across the resistor increases.
B)the current flowing in the circuit increases.
C)the current flowing in the circuit decreases.
D)the current flowing in the circuit does not change.

Question

Quizplus · Accepted Answer

Inserting an ammeter in series adds a small resistance to the circuit, which slightly decreases the total current flowing through the circuit.
