A single-cell battery is connected to a resistor valued at $33 \text{ ohms} \pm 10\%$. An ammeter is inserted in series between the battery and the resistor. The ammeter has a three digit display that reads $0.02\text{ amps}$.

Which of the following statements regarding this circuit are true?

Select TWO answers.

A

The battery might produce a terminal voltage as high as $0.75\text{ volts}$.

B

The voltage drop across the resistor is approximately $160\text{ volts} \pm 20\text{ volts}$.

C

The actual value of the resistor might be as high as $42\text{ ohms}$.

D

An ammeter reading of $0.02\text{ amps}$ has a larger percent uncertainty than a reading of $0.08\text{ amps}$.
