-**Known Values**
+**Known Values** R1 = 60Ω, R2 = 120Ω, U = 12V
-R1 = 60Ω, R2 = 120Ω, U = 12V
-**Unknown Values**
+**Unknown Values** Rges, I, U1, U2
-Rges, I, U1, U2
-**Solution**
+**Solution** Rges = R1 + R2 = 60Ω + 120Ω = 180Ω   I = U / Rges = 12V / 180Ω = 0.067 A   U1 = I * R1 = 0.067A * 60Ω = 4V   U2 = I * R2 = 0.067A * 120Ω = 8V
-Rges = R1 + R2 = 60Ω + 120Ω = 180Ω
-I = U / Rges = 12V / 180Ω = 0.067 A
-U1 = I * R1 = 0.067A * 60Ω = 4V
-U2 = I * R2 = 0.067A * 120Ω = 8V

 === Dangers: ===
   * If you are working on a circuit, disconnect the power supply first!
   * We only use voltages up to 12V, never above!
