Express your answer using two significant figures. SubRR My Answers Part B What the voltage across each is resistor? Express your answer using two significant figures. My Answers Part Express del ered to the your answer resistor? using two significant fogures. 2017 Student Library Research Award

Explanation / Answer

NEt Resistance in parallel = 1/Rnet = 1/R1 + 1/R2 +1/R3

here

1/Rnet = 1/1.3 + 1/2.7 +1/4.6   

Rnet = 0.7407 ohms

-------------------------------------

IN parllel combination, same voltage passes

so

So Volatge across R1 = R2 = R2 = 6 V

------------------

c. Power Across 4.6 ohms = P = V^2/R

P = 6^2/4.6

P = 7.82 Watts
