How did your predictions compare with the answers from PhET? Now right click on one of the resistors. Here you can change the resistance. Change the voltage of each resistor. You can repeat this with the battery to change the voltage. What do you need to do to get the light bulb to glow the brightest? What do you need to do to get the light bulb to glow the dimmest? Part 2 Parallel Circuits First draw a schematic diagram of a --- , --- D, and light bulb in parallel with a ---- volt battery
