Why induced current in a coil opposes the EMF producing it?

What is the direction of induced current in lenzs law?
According to Lenz's Law, the direction of the induced current is such that it opposes the change in magnetic flux that produced it. If the magnetic field through a loop is increasing, the induced current will flow in a direction that creates a magnetic field opposing that increase. Conversely, if the magnetic field is decreasing, the induced current will flow in a direction that attempts to maintain the original magnetic field. This principle ensures the conservation of energy in electromagnetic systems.
How do you find average back emf?
Normally emf can be calculated by the following formula e=N*(dф/dt) where dф/dt = rate of change of flux linkages In actual practice it is given as e=-[N*(dф/dt) ] because as per lenzs law the voltage induced in a direction to oppose the very cause for it i.e., change in flux linkages. vydehi
What is the power dissipated by a parallel resistor of 100 ohms with a 40v power source?
You may find it helpful to use Ohm's law and the definition of electrical power.
How are currrent voltage and resistance related by Ohms Law?
They're not! The relationship you describe is derived from the definition of the ohm, not from Ohm's Law. This tells us that resistance is equal to the voltage divided by the current. Ohm's Law merely tells us that the ratio of voltage to current is constant for variations in voltage -which, unfortunately, is not actually true. In other words, Ohm's Law is not true!
