TED-Ed: The science of static electricity - Anuradha Bhagwat
We've all had the experience: you're walking across a soft carpet, you reach for the doorknob and - ZAP. But what causes this trademark jolt of static electricity? Anuradha Bhagwat sheds light on the phenomenon by examining the nature of...

Electrostatic Induction
In this video Paul Andersen explains how the charge distribution can be affected my electric forces produced by a charged object. In an insulator charges are fixed but in conductors the charges can move. Induction occurs when the charges...

Resistivity
In this video Paul Andersen explains how the resistivity of a material opposes the flow of charge. Conductors (like metal) will have a low resistivity and insulators will have a high resistivity. Semiconductors will have a moderate...
