ELECTRICITY Static Electricity Static electricity is when a charge is built up on an object. The charges do not move. This is usually caused by friction.

Chapter 7 Electricity. An atom is the basic unit of matter and is made of protons, neutrons, & electrons – protons: + charge – electrons: - charge – neutrons:

Presentation transcript:

Static Electricity Shock When you shuffle your feet across a carpet, your body becomes charged. The effect of this charge is that your entire body represents a voltage potential. When you touch a metal doorknob, a voltage difference is created between you and the doorknob, and current flows. The conduction material is air, not your body! If the model of the space between your hand and the doorknob is a 1MΩ resistance, what voltage potential exists between your hand and the doorknob if the current causing the mild shock is 3 mA?
