2:03 Tte 0 . L Virtual+Circuits+lab-nE Virtual Circuits lab: Link to website https://phet.colorado.edu/en/simulations/circuit-construction-kit-dc-virtual-lab In this lab we will be exploring DC circuits - DC means direct current - current provided by the energy stored in a battery, measured in Volts. Although we have AC (alternating current) in our homes, understanding DC circuits provides the foundation for later study and analysis of AC circuits, and many of our appliances run off of direct current. For example, your laptop, your phone, or tablet, basically any device with a battery runs on Direct Current. That big box that plugs into the wall converts AC to DC. For this lab you need to know Ohm's law: V = IR Where V is voltage, I is current, and R is resistance. Ohm's law allows you to calculate the voltage across any device in the circuit. We will explore two different types of circuits - series and parallel. The words series and parallel refer to how the resistors in the cir it. A series circuit has the resistors all in a line, a parallel circuit has the resistors lined up parallel to each other . Let's start with the simplest circuit we can imagine, just a battery and a resistor. There are wo devices we use to measure current and voltage - the ammeter measures current and has to be built into the circuit. The Voltmeter measures voltage, and to use this you put the probes on either side of the device that you want to measure the voltage of. In the upper right part of the screen click show current conventional. Wire Bamery Light Bulb Advanced Voltage 9.00 V 1. Before we get started with our circuit, let's pull out a battery and measure the voltage. You can adjust the battery voltage by clicking on the battery. . You should get a reading of 9V. do you?
