2) C.is independent of the charge on the capacitor

Answer 4

In a parallel circuit

B .the potential drop is the same for each element of the circuit.

The capacitance of a parallel plate capacitor:

C is independent of the charge on the capacitor

Answer 5

1.

In a parallel circuit, the voltage drop across each element of the circuit is the same. But, the totaal current

is equal to the sum of cuurents in each element in the circuit. Heat generated in the circuit depends on voltage

drop and current, so it does not same in each element in the circuit. Therefore, option B is correct.

2.

The capacitance of a parallel plate capacitor:

                  C = e₀A/d

From the above relation it is clear that the capacitance of the parallel plate capacitor

is not depending on charge stored on it or voltage across the capacitor.

The cpacitance of the capacitor is inversely propotional to the distance between the plates.

So, it is depending on the distance between them.

In dielectric material case, the capacitance is,

           C = ke₀A/d

The capacitance of the parallel plate capacitor is directly proportional to dielectric constant.

So, it increases with dieclectric constant.

Therefore, option C is correct.
