Question

What is the total current going through the circuit shown?

A. 0.28 A

B. 0.80 A

C. 3.6 A

D. 4.0 A

Answer 1

here the total resistance is:
\[\Large R = \frac{1}{{\frac{1}{{10}} + \frac{1}{5}}} = ...\]

Answer 2

3.333 ?

Answer 3

ok!

Answer 4

then, I apply the Ohm's law, and I get:
\[\Large I = \frac{{\Delta V}}{R} = \frac{{12}}{{10.333}}\]

Answer 5

oops...
\[\Large I = \frac{{\Delta V}}{R} = \frac{{12}}{{3.333}}\]

Answer 6

3.6? so choice C is our solution?

Answer 7

that's right!

Answer 8

yay! thanks!:)

Answer 9
