This app allows you to design and solve a Direct Curent (DC) circuit with the following possible components:

- oriented sources
- resistors
- junctions
- wires

For each source, it lets you input the generated voltage and inner resistance. For each resistor it lets you specify the value of the resistance.

No matter how complex your circuit, we find your currents and wattages!

If the circuit is simple (single loop), we apply Ohm's law (U = R x I) and we find the current. Then we find the wattages with the formula P = U x I = R x I^2.
If the circuit is complex, by applying graph algorithms to isolate simple loops in the circuit, and then using Kirchhoff's first and second law, we extract a system of linear equations whose variables are the very currents you want to know. Then we solve the system and show you the solution!
