I did a physics lab and got some values. I want to check them theoretically to see how the results differ. From this diagram, answer the following questions: The laws to be verified included the conservation of current in a node, the addition of potentials for components in series, and the addition of currents for components in parallel. The data : R1: 1094 ohm R2 : 998 ohm R3: 1094 ohmR4: 25 ohm Source 1 : 5 V
Source 2 : 1.5 V
Two resistances R1 and R2 are connected in parallel. We know that R1=90 Ω and thatthe current through R2 is three times the value of the current through R1.Determine the value of R2.
