Question

In this circuit, the greatest voltage drop will occur across which resistor?

A. R1

B. R2

C. R3

D. Voltage will drop equally across each resistor.

Answer 1

here the total resistance is:
R=2+4+5=...

Answer 2

11?

Answer 3

ok!

Answer 4

and the current is:
I= 12/11 amperes
so the voltage drop across R_1, is:
V_1= (12/11)*2=...

Answer 5

we get 2.18?

Answer 6

ok!
the voltage drop across R_2 is:
V_2=(12/11)*4=...
the voltage drop across R_3, is:
V_3=(12/11)*5=...

Answer 7

4.36

and

5.45

?

Answer 8

so, which is the highest one?

Answer 9

V3? so does that mean R3 is our solution?

Answer 10

yes!

Answer 11

yay! thanks!!:)

Answer 12
