Consider the circuit shown below. Battery emf is ε=6V and the resistance are R1=39Ω, R2=59Ω and R3=10Ω. The current through R1 does not change whether the two switches S1 and S2 are both open or both closed. Use this clue to determine the value of the unknown resistance R. Express your answers in units of Ω using zero decimal places.
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
