two resistors, r1 = 25.0 ohms and r2 = 64.0 ohms, are connected in parallel. r1 has a 0.200 a current flowing through it. what is the current through r2? (remember, resistors in parallel have the same v.) (unit = a)

Answer

Explanation:

Step1: Calculate voltage across R1

Use Ohm's law $V = I_1R_1$. $V=0.200\times25.0 = 5.00$ V

Step2: Calculate current through R2

Since voltage across parallel - connected resistors is the same, use Ohm's law for R2, $I_2=\frac{V}{R_2}$. $I_2=\frac{5.00}{64.0}= 0.078125$ A

Answer:

$0.0781$ A
