What is an ideal capacitor?

Hint: A capacitor was designed in order to store and release electricity in a circuit. Also, it is used widely for blocking direct current and allowing alternating current to flow through the circuit. We will take into consideration the concept of working of the capacitor. Then, we will consider the ideal working of the device.

Complete step by step solution:
For an ideal case, the capacitor will store the total current flowing through it and then will completely release it. Also, in an ideal case, the capacitor will not allow any amount of direct current through it and will allow the total alternating current.
Also, For an electronic device to be an ideal situation, the device should not offer any resistance to the inflowing current in the circuit.
Hence, in total we can say that an ideal capacitor which stores the total current flowing through it and then will completely release it. Also, it will not allow any amount of direct current through it and will allow the total alternating current. An ideal capacitor is a purely reactive device and offers no resistance or in other words it has no resistive effect. Also, it is not affected by the change in temperature in the surroundings.

Note: Students should be very much cautious while defining the ideal case of a device as sometimes students often commit errors while doing the same. The above point should be also kept in mind while defining the ideal case of any phenomenon.
