State whether the given statement is true or false?
A capacitor blocks A.C. but passes D.C.
(a) True
(b) False
Solution
By the use of definitions of alternating and direct current we can find that as the capacitor stores electric charges, it is much comfortable for the capacitor to store a charge with no steadiness in it. With the help of this information we will get the right option.
Complete step by step answer:
Capacitor: We will find that a capacitor is a type of a technical device which is used for the storage of electronic charges. This consists of two plates which are metallic. These either are in vacuum or it is found as separated by a dielectric. In our daily life we will find the capacitor in cars.
A.C. : We use A.C. for defining alternating current. By the term alternating current we mean the flow of electrical charges in back and forth directions. It is cheaper than the D.C. current and we use it more often in our daily life.
D.C. : It is a direct current flow which only flows in one direction only. It is not that cheap than the alternating current and it is a little more complex than that.
The main difference between the alternating current and direct current is that A.C. includes two slippery rings which help in the generation of magnetic fields by the magnets around the circuit whereas we use only split rings to get in the flow.
When a circuit consists of a capacitor and a D.C. then after reaching a steady state the capacitor starts to block the current but when an alternating current is applied in the circuit containing capacitor then, by the back and forth action of the current the capacitor does not block the A.C.
So, the correct answer is “Option B”.
Note: Try to consider the following points for information related to the question.
(1) It is understood by the definition of capacitor that any type of a device which is used to store electric charges will rely upon those types of current which do try to flow in the circuit without causing hindrance.
(2) Clearly, if we see that as A.C. is used in cars it is important to have a combination of a capacitor and a current which does not break the circuit.
