Answer #1

a)

e = L di/dt

e = 0.14* 0.08 / (16* 10^-6)

e = 700 V

=====

b)

potential increases

    faraday's law of electromagnetic induction says that if there is relative motion between any conductor and magnetic field an induced emf is induced in the conductor and if the conductor is cloesd loop then induced current will also start to flow. my question is that where are the points on the loop across which the potential difference generated so that current can flow, because the current flows only due to potential difference

    What is Faraday's Law? o It defines the induced voltage across a coil when the magnetic field going through it changes. o It gives the direction of the induced current going through a coil when the magnetic field going through it changes. O The potential difference across a resistor is proportional to both the resistance and the current going through it O The sum of all the current going into a junction has to equal the sum of all the...

    4. A practical galvanic cell is colloquially known as a "battery". Is Faraday's law in any way applicable to using a battery (hence a galvanic cell)? If so, how? (Hint: Did you see the waterfall or water + gravity analogy in the tutorial? Difference in height is not the only important waterfall parameter). 5. Ideally, determination of cell emf is a steady-state experiment with no net change in concentrations of ions and no current flowing. However, using a battery (galvanic...
