## Flashcards
##### ![PHOTO POTENTIAL DIVIDER](potential-divider.jpg) If the resistance of $R_1$ is twice that of $R_2$, how much more of the total potential difference does $R_1$ get??
Twice as much.

##### What is the potential divider equation??
$$
V_{\text{out}} = V_{\text{in}} \times \frac{R_1}{R_1 + R_2}
$$
