Question

For this circuit, what will be the voltage drop across R2?

A. 3.3 V

B. 17 V

C. 25 V

D. 45 V

Answer 1

total resistance is:
R= 2+10+15=...

Answer 2

27!

Answer 3

ok! so the current is:
I= 45/27=...

Answer 4

ermm i get 1.6666666667

so about 1.67?

Answer 5

Current is:I=1.67 mA= 1.67*10^(-3) amperes
so the requested voltage drop is:
V_2= 10^4*1.67*10^(-3)=...volts

Answer 6

we get this? 16.7?? so choice B (17 V) is our solution?

Answer 7

yes!

Answer 8

yay! :) i can post the next one?

Answer 9

yes!

Answer 10

okie! :D

Answer 11

:)
