Question

Indicate true or false for each of the following statements:
1.The capacitance of four capacitors placed in parallel with each other is the sum of their individual values.
2.Electrons flow in the opposite direction to conventional electric current.
3.A superconductor has zero resistance independant of temperature.
4.Electric charge travels at the speed of light in a wire.
5.The capacitance of a parallel plate capacitor is inversely proportional to the area of the plates.

I cannot figure it out please help

Explanation / Answer

1. equivalent capacitance when connected in series.

Ceq = C1 + C2 + C3 + .....

True

2. I = q/t

so current is flow rate of charge.

and charge on electrone is negative.

I = - Qe / t

hence direction flow speed of electron is opposite of current direction.

True

3. Yes, Superconductor have zero resistance.

True

4. False

5. C = e0 A / d

C is directly propotional to the area of plate.

False
