Question

For the circuit drawn inside, what will be the voltage drop across R_2?

A. 9.47 V
B. 14.2 V
C. 21.3 V
D. 45.0 V

Answer 1

When you combine all of the resistors...what do you get for the equivalent resistance?

Answer 2

95?

Answer 3

Correct...

so if we were to redraw our circuit now...



What would be the total current going through the resistor?

Answer 4

45?

Answer 5

Current, not Voltage :)

\[\large I = \frac{V}{R}\]

Answer 6

oh oops! so 45/95? = 0.47? :/

Answer 7

Right...that is our current that goes through our entire circuit here

Now that we know that, we break apart our circuit again to the original with the current drawn in
