If R1= 1Ω, R2=2Ω and Ru=3Ω, (a) to what value the Rvar should be adjusted so as to achieve balance condition? (b)If V0 = 6 V, Ra = 0.1 Ω(resistance in the meter), and Ru were then to deviate by a small amount to Ru = 3.01 Ω, what would be the reading on the ammeter?
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.
