This lab shows the spiral path followed by a positively charged particle (in red) in a uniform magnetic field. Also shown are the two components of the motion.
LAB
In this lab, you can investigate the trail of a charged particle. You can change the direction of the magnetic field and the magnitude and sign of the charge to draw patterns on the screen. Explore the different patterns you can make.
LAB
In this lab, you can investigate the force that a magnetic field exerts on a charged particle. This force has some things in common with the force an electric field exerts on a charged particle, but there are also key differences between them.
LAB
This lab shows power boxes for a series RC circuit.
The concept of power boxes was introduced in a September 2018 article in The Physics Teacher, by Daryl McPadden, Jason Dowd, and Eric Brewe, titled "Power Boxes: New Representation for Analyzing DC Circuits".
LAB
This lab shows a resistor-capacitor series circuit, involving a resistor, a capacitor, a battery, and a switch. Note that on the voltage graph, the red line shows the voltage across the resistor, and the blue line shows the voltage across the capacitor.
LAB
This lab shows power boxes for a circuit that can have resistors in series and parallel, depending on the switches.

LAB
This lab aims to acquaint you with the concept of power boxes (McPadden, Dowd, and Brewe, 2018). Note that one way to calculate power is to multiply the voltage and the current.
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. You can also sketch a current vs.
