SUMMARY

Ohm's Law, represented by the equation U=IR, is directly applicable to parallel circuits, where the voltage across each component remains constant. In the discussion, a current of 200mA (0.2A) through a resistor of 50 ohms results in a voltage of 10V, confirming that the source voltage in a parallel circuit is also 10V. This illustrates the fundamental principle that in parallel circuits, the voltage is the same across all components, regardless of the individual resistances.

*U=voltage

Homework Equations

U=IR (V=IR)

The Attempt at a Solution

200mA=0,2A --> 0,2*50=10V...? So because it's parallel the source should be 10V too right?
