Question

Four resistors, with R1 = 3.0 Ω, R2 = 4.0 Ω, R3 = 6.0 Ω, R4 = 9.0 Ω are connected as shown in the figure. We want a current of I2 = 5.0 A to flow through resistor R2. 1) What potential difference must be applied across the external terminals? 2) What is the current flowing through R1? 3) What is the current flowing through R3? 4) What is the current flowing through R4? 5) What is the net resistance of this circuit?

Step 1

We can see that R3 and R4 are in parallel, so their equivalent resistance is: $$ \frac{1}{R_{34}} = \frac{1}{R_3} + \frac{1}{R_4} = \frac{1}{6.0} + \frac{1}{9.0} $$ $$ R_{34} = \frac{1}{\frac{1}{6.0} + \frac{1}{9.0}} = 3.6\,\text{Ω} $$ Now, R2 and R34 are in Show more…
