In this lab, you can visualize the charge flow around a circuit, and see what happens when the battery voltage or the resistor resistance is changed. You can also sketch a current vs.
LAB
In this lab, you can visualize the charge flow around a circuit, and see what happens when the battery voltage or the resistor resistance is changed using the options shown below.
What happens to the charge flow when you increase/decrease the resistance?
LAB
The lab shows a simple circuit, with a battery, a switch, a resistor, and a few wires. Conventional current shows the Ben Franklin view of the circuit, that the flowing charges are positive (shown in red).
LAB
This lab shows the equilibrium position of a charged ball on a string.
LAB
In this lab, you can observe the simulation of a charged particle being launched horizontally into a uniform electric field that is directed down.
LAB
In this lab, you can explore the connections between Force, Field, Potential Energy, and Potential. On the left is a representation of a 4 m x 4 m space in which there is a uniform field directed down. If you choose a ball, then the field is a gravitational field.
LAB
Click-and-drag the particles to move them left or right. The particle on the left is confined to the region to the left of the origin; the particle on the right is confined to the region to the right of the origin.
LAB
In this lab, you can investigate the electrostatic potential energy associated with two interacting charged particles, as well as the force that one charged particle exerts on the other. Note that the arrows attached to the particles are force arrows.
LAB
In this lab, you can investigate the electrostatic potential energy associated with two interacting charged particles, and how that potential energy varies with the distance between the particles.
LAB
The lab shows the electric field near two charged particles.
If the particle is drawn in red, it has a positive charge.
If the particle is drawn in blue, it has a negative charge.
