- 2. To explore resistors in series and parallel, we will use a virtual lab for DC circuits. Open your web browser and go to the following site: https://phet.colorado.edu/sims/html/circuit-construction-kit-dc/latest/circuit-construction- kit-dc_en.html (a) Construct a circuit with resistors (or light bulbs) in series and record current and voltage. How does the current through the resistor (or the bulb) in a single-resistor circuit with the current through the same resistor when it is connected in compare series with a second resistor?
