    For Gauss's law we have to prove 1/£° time of charge ..... So We have E•dS where as E is electric field intensity and S is surface area of sphere now We have studied that E=kq/r^2 And k=1/4π£°(1 by 4 pie epsilon not) Now put value of both E and s in E•ds S=4πr^2 (4 pie r squ•) Now 4πr^2 and 4πr^2 will be cancel out and you will get 1/£°(1 by Epsilon not) Note:- for removing d you have have to take cos 0 because when you will draw a circle you will get to know why i took cos 0°(cos0°=1)

    The average ac power is found by multiplying the rms values of current and voltage. Ohm's law for the rms ac is found by dividing the rms voltage by the impedance. In an ac circuit, there is a phase angle between the source voltage and the current, which can be found by dividing the resistance by the impedance.

    Phir bhi... Carbon resistors are made up of carbon compound. More the carbon content in the resistor less is the resistivity. They are used in small electrical circuits.
