1. If there is a current of 10 amperes in a circuit for 10 minutes, what quantity of electric charge flows in through the circuit? 2. How much current must there be in a circuit if 100 coulombs flow past a point in the circuit in 4 seconds? 3.
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=?
Worksheet - Coulomb’s Law 1. A negative charge of - 2.0 C and a positive charge of 3.0 C are separated by 80 m. What is the force between the two charges? 2. A negative charge of - 0.0005 C exerts an attractive force of 9.0 N on a second charge that is 10 m away. What is the magnitude of the second charge? 3.
Key learning points. Electric charge, Q, is measured in coulombs (C). Electric current is a measure of the rate of flow of electric charge, calculated using: I = Q ÷ t. Potential difference is a measure of the energy transferred by each coulomb of charge, calculated using: V = E ÷ Q.
Electric Charge Calculations. Electric charge is a property of matter where it experiences a force when in an electromagnetic field. The idea behind it is: Fundamental particles can have 0, +1 or −1 electric charge: + and − are pulled towards each other. + pushes + away. − pushes − away.
Calculate the electrical charge and current with these worksheets. Electrical circuits may seem like an impossible feat to understand for students still trying to figure out what they are and how they work, but it doesn't have to be.
Teacher Toolkit. Topic: Charge and Charging. Objectives: To use and understanding of atomic structure to describe how objects become charged by the additional or removal of electrons. To identify the type of charge on an object by observing its interactions with other charged and neutral objects.
