Suppose the emf of the battery in the circuit shown in the figure varies with time t so that the current is given by i(t) = 2.50 + 6.00t, where i is in amperes and t is in seconds. Take R = 4.50 Ω and L = 4.00 H, and find the emf required of the battery at t = 6.00 s.
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.
