solve these physics qustions in the photoKnowing that the ammeter must be connected in series with the circuit and the voltmeter must

be connected in parallel, this tells you about the internal resistance of each device that: choose

the correct answer:

a$-R_{\text{v}\text{o}\text{l}\text{t}\text{m}\text{i}\text{c}\text{t}\text{e}\text{r}}$ approach to zero and $R_{\text{a}\text{m}\text{m}\text{e}\text{t}\text{e}\text{r}}$ approach to infinity

b$-R_{\text{v}\text{o}\text{l}\text{t}\text{i}\text{n}\text{c}\text{t}\text{e}\text{r}}$ approach to infinity and $R_{\text{a}\text{m}\text{m}\text{e}\text{c}\text{r}}$ approach to zero

c$-R_{\text{m}\text{o}\text{l}\text{t}\text{m}\text{e}\text{t}\text{e}\text{r}}$ and $R_{\text{a}\text{m}\text{m}\text{e}\text{t}\text{e}\text{r}}$ approach to infinity

$d-R_{\text{i}\text{n}\text{l}\text{i}\text{n}\text{e}\text{t}\text{e}\text{r}}$ and $R_{\text{a}\text{n}\text{m}\text{i}\text{e}\text{r}\text{e}}$ approach to zero
