The image displays an electrical circuit diagram with three resistors and a battery. The resistors have the following resistances: - A 20Ω resistor is connected in series with the battery. - Two resistors, one 15Ω and the other 30Ω, are connected in parallel. The battery is represented by the symbol with an electromotive force labeled as "E". The 15Ω and 30Ω resistors are connected in parallel to each other, and this parallel combination is connected in series with the 20Ω resistor and the battery.
