Question
Consider the circuit in Figure $\mathrm{P} 19.55,$ with resistors $R_{1}=750 \Omega, R_{2}=250 \Omega,$ and $R_{3}=420$ \Omega. For what value of resistor $R_{4}$ is the current through resistor $R_{5}$ zero?
Step 1
This can be written as: \[V_{a} = V_{b}\] where $V_{a}$ is the potential difference across $R_{1}$ and $R_{2}$ and $V_{b}$ is the potential difference across $R_{3}$ and $R_{4}$. Show more…

In the circuit shown in the figure, $V_{1}=1.50 \mathrm{~V}, V_{2}=2.50 \mathrm{~V}$ $R_{1}=4.00 \Omega$, and $R_{2}=5.00 \Omega$. What is the magnitude of the current, $i_{1}$, flowing through resistor $R_{1}$ ?
Refer to the accompanying diagram (Figure $\mathrm{Pl} 7.58$ ). If $\mathcal{E}=9.0 \mathrm{~V}, R_{1}=150 \Omega, R_{2}=250 \Omega,$ and $R_{3}=1000 \Omega$ find the current in each resistor.
