Frame of reference:When the position of a particle in space changes with time, it is said to be in motion. To describe motion, a frame of reference is needed first and foremost. The set of spatial coordinates...
It is defined as the angle between resultant current and voltage in AC circuit. it is represented by COS PHI In case of a pure resistor, the angle between the voltage and current is equal to zero hence...
Point 1: For case for ground pin. Also ground pin is larger that other two pins so that it would be the first to go into the hole and the last to come out of the hole just for sake of safety Point 2:...
