Question
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.
Step 1
We see that $R_2$ and $R_3$ are in parallel, so we can find their equivalent resistance $R_{23}$ using the formula for resistors in parallel: \[ \frac{1}{R_{23}} = \frac{1}{R_2} + \frac{1}{R_3} \] Substituting the given values, we get: \[ \frac{1}{R_{23}} = Show more…
