Question

27.1 single - loop circuits. a single loop circuit contains a 2.0 v battery and has a current of 0.80 a. what is the total resistance in the circuit? o 2.5 ω o 0.40 ω o 1.2 ω o 2.8 ω save for later submit answer

Explanation:

Step1: Recall Ohm's law

$V = IR$, where $V$ is voltage, $I$ is current, and $R$ is resistance. We need to find $R$, and we can re - arrange the formula to $R=\frac{V}{I}$.

Step2: Substitute given values

Given $V = 2.0\ V$ and $I=0.80\ A$. Then $R=\frac{2.0\ V}{0.80\ A}=2.5\ \Omega$.

Answer:

$2.5\ \Omega$
