Description
5 February Connect a battery to a pair of plates. Charges move. This creates a potential difference (ΔV) ΔV Which creates a field (E = Δd ) Which exerts forces on charges (F = qE) If you can’t get inside or get away, you should do the “lightning crouch.” Feet close together, heels up Lessen potential difference between your feet The electron gun in a CRT television works like this. A filament heats up, and electrons come off. The filament is grounded; its potential is 0 V. At some distance, a metal plate with an aperture set is set at a potential of 150 V. The electron accelerates toward the positive plate, then continues through the aperture. What is the direction of the electric fiel
