Find the potential difference between points- $A$ and $-B$ in Fig. $26-5$ if $R$ is $0.70 \Omega$. Which point is at the higher potential?
Added by Erica L.
Step 1
We can use Ohm's Law to find the current: $I = \frac{V}{R}$ where $V$ is the potential difference across the resistor $R$ and $R$ is the resistance. Show more…

(a) Calculate the potential difference between points $a$ and $b$ in Figure P 18.47 and (b) identify which point is at the higher potential.
In Fig. $27-9$ , what is the potential difference $V_{d}-V_{c}$ between points $d$ and $c$ if $\mathscr{E}_{1}=4.0 \mathrm{V}, \mathscr{E}_{2}=1.0 \mathrm{V}, R_{1}=R_{2}=10 \Omega,$ and $R_{3}=$ $5.0 \Omega,$ and the battery is ideal?
