# Problem: (a) What is the potential difference across the 10 Ω resistor in the figure ?(b) What is the potential difference across the 20 Ω resistor in the figure?

###### FREE Expert Solution

Current is the same for resistors in series.

The sum of potential differences across 10Ω and 20Ω resistors should be equivalent to 15V

Potential difference is given by:

$\overline{){\mathbf{V}}{\mathbf{=}}{\mathbf{i}}{\mathbf{R}}}$
