The Charging Interactive allows users to explore charge interactions, the charging of objects by conduction and induction, and the grounding of objects. This HTML5 Interactive includes two modes - Practice mode and Play mode.
Electrical charge is measured in Coulombs \text{(C)} and current is measured in amperes \text{(A)}. The current can be thought of as the rate of flow of charge around the circuit. You can measure current using an ammeter. You can calculate the charge that has flown around a circuit in a certain time \text{(s)} using the following equation:
Arrange positive and negative charges in space and view the resulting electric field and electrostatic potential. Plot equipotential lines and discover their relationship to the electric field. Create models of dipoles, capacitors, and more!
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. How much time is required for 10 coulombs of charge to flow past a point if the rate of flow
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.
To use Coulomb’s Law equation to algebraically solve for an unknown quantity (F, d, Θ 1 or Θ 2) 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.
