Introduction AC is defined as alternating current due to bidirectional flow and representing by Sinusoidal current because of sine function . we just giving few important questions related to ac .1 In a light bulb connected to an ac source the instantaneous current is zero two times in each cycle of the current. Why does […]

What Are Conductive vs. Insulative Materials?Electrostatic discharge (ESD) happens from friction between conductive and less conductive or non-conductive materials. Non-conductive, or insulative, materials have high surface resistivity, limiting electrons’ flow over and through the material. Static charges are difficult to ground and remain on the surface of these materials. On the other hand, conductive materials […]
