# A circuit consists of a \(24\text{ V}\) ideal power supply connected in series with three resistors having resistances of \(10\text{ }\Omega\), \(20\text{ }\Omega\), and \(30\text{ }\Omega\). What is the electric potential difference across the \(20\text{ }\Omega\) resistor?

A circuit consists of a \(24\text{ V}\) ideal power supply connected in series with three resistors having resistances of \(10\text{ }\Omega\), \(20\text{ }\Omega\), and \(30\text{ }\Omega\). What is the electric potential difference across the \(20\text{ }\Omega\) resistor?

![A single closed rectangular circuit diagram. On the vertical left wire, an ideal DC battery symbol is shown with a long horizontal line above a short horizontal line, labeled \(24\text{ V}\). The top horizontal wire contains a single zig-zag resistor symbol labeled \(10\text{ }\Omega\). The right vertical wire contains a single zig-zag resistor symbol labeled \(20\text{ }\Omega\). The bottom horizontal wire contains a single zig-zag resistor symbol labeled \(30\text{ }\Omega\). Plain solid black lines connect the four elements into a single continuous loop. No other labels, meters, or components appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787459666-z2D9Zn.jpg)

- **A.** \(4.0\text{ V}\)
- **B.** \(8.0\text{ V}\)
- **C.** \(12\text{ V}\)
- **D.** \(16\text{ V}\)
