    The mechanism of operation in a capacitor

    The DC doesnt flow through capacitor. I thought it was because the electrons jus get saturated on one side and are lost on other side, such that it can’t take or give up anymore or plausibly due to voltage developed across it whereas in AC as directions keep changing, saturation doesnt occur. But it if [...]

    What is meant by charge on a capacitor?

    Mohit asked this question: "What is meant by charge on a capacitor?" Answer: As we know, a simple capacitor (say a parallel plate capacitor) consists of two plates parallel to each other. When charged, charge on either plate of the capacitor is called charge on the capacitor. The following links will help you explore further … Continue reading What is meant by charge on a capacitor?

    CBSE Question Paper 2007

    SET -1 In a series LCR circuit, the voltages across an inductor, a capacitor and a resisitor are 30 V, 30V and 60 V respectively. What is the phase difference between the applied voltage and the current in the circuit? Ultraviolet radiations of different frequencies f1 and f2 are incident on two photosensitive materials having … Continue reading CBSE Question Paper 2007
