Step 1
Since the resistors are in parallel, we use the formula for total resistance in a parallel circuit: 1/R_total = 1/R1 + 1/R2 + 1/R3 Substituting the given values: 1/R_total = 1/1.20 + 1/1.20 + 1/1.20 = 2.5 kΩ^-1 Therefore, R_total = 1/2.5 = 0.4 kΩ Show more…

Each In Fig. $27-27$ find the current in each resistor and the potential difference between points $a$ and $b$. Put $\Delta V_{\mathrm{B} 1}=6.0 \mathrm{~V}$, $\Delta V_{\mathrm{B} 2}=5.0 \mathrm{~V}, \Delta V_{\mathrm{B} 3}=4.0 \mathrm{~V}, R_{1}=$ $100 \Omega$, and $R_{2}=50 \Omega$.
(II) For the circuit shown in Fig. $47,$ find the potential difference between points a and b. Each resistor has $R=130 \Omega$ and each battery is 1.5 $\mathrm{V}$.
