Question

A capacitor of capacitance C is charged to a potential difference V from a cell and then disconnected from it. A charge +Q is now given to its positive plate. The potential difference across the capacitor is now

  1. V
  2. V plus Q over C
  3. V plus fraction numerator Q over denominator 2 C end fraction
  4. V minus Q over C comma times i f times V less than C V

The correct answer is: V plus fraction numerator Q over denominator 2 C end fraction

A physics lab is designed to study the transfer of electrical energy from one circuit to another by means of a magnetic field using simple transformers. Each transformer has two coils of wire electrically insulated from each other but wound a round a common core of ferromagnetic material. The two wires are close together but do not touch each other

The primary  coil is connected to a sorce of alternating  current. The secondary  coil is connected to resistor such as a light bulb. The AC source produces an oscillating voltage and current in the primary coil that produces an oscillating magnetic field in the core material. This in turn induces an oscillating voltage and AC current in the secondary coil
Students collected the following data comparing the number of turns per coil (N), the voltage (V) and the current (I) in the coils of three transformers.
