Question

For the network shown in the figure below: The top branch between a and b consists of two 1.0 ? resistors in series. The lower left branch from a to the bottom node is 3.0 ?; the lower right branch from b to the bottom node is 5.0 ?. A) What is the equivalent resistance? Enter your answer to two significant figures. B) If the voltage difference between a and b is 12 V, what is the current through the 5.0 ? resistor? Enter your answer to two significant figures.

Step 1

0 Ω and 10.0 Ω resistors in parallel. The formula for resistors in parallel is: $$\frac{1}{R_{eq}} = \frac{1}{R_1} + \frac{1}{R_2}$$ Plugging in the values, we get: $$\frac{1}{R_{eq}} = \frac{1}{5.0} + \frac{1}{10.0}$$ $$\frac{1}{R_{eq}} = Show more…
