Electrical Current, Charge and Potential Worksheet. 1. Calculate the unknown quantity. (a) I = 0.4 A, t = 20 s. Q = ? (b) Q = 240 C, t = 300 s, I = ? (c) I = 2 A, Q = 400 C, t=?
To use Coulomb’s Law equation to algebraically solve for an unknown quantity (F, d, Q1 or Q2) in a physics word problem. To combine Coulomb’s Law equation with Newton’s second law, free-body diagrams and trigonometric functions to analyze physical situations that include interacting charges.
Conductors are materials in which charges can move about freely; insula-tors are materials in which electric charge is not easily transported. Electric charge can be measured using the law for the forces between charges (Coulomb’s Law). Charge is a scalar and is measured in coulombs 1.
Charges, Coulomb’s Law, and Electric Fields Some experimental facts: Experimental fact 1: Electric charge comes in two types, which we call (+) and (−). An atom consists of a heavy (+) charged nucleus surrounded by light (−) electrons. nucleus = (+) charged protons and (0) charged neutrons
The three basic principles for this tutorial can be explained using electrons, or more specifically, the charge they create: Voltage is the difference in charge between two points. Current is the rate at which charge is flowing. Resistance is a material's tendency to resist the flow of charge (current).
Charging an Object Section 12.1. Each of the diagrams in Student Worksheets 12.1B–12.1C represent a method of charging an object. Explain the steps involved in each method and indicate on the diagram, using the flow of electrons.
To identify the type of charge on an object by observing its interactions with other charged and neutral objects. To describe what charge polarization is and to use an understanding of the distinction between insulators and conductors to explain how and why polarization occurs.
