WebbEngineering Electrical Engineering what is the power absorbed of two identical resistors are connected in series to 10v source. one resistor has a value of 2 ohms A. 2.5 W B. 5W … WebbSo then, for two ohm resistor to calculate the current here, I would substitute R as two, V is 50, calculate the current. Then for 40 Ohm resistor, I would put V is 50, that's already given, R is 40. Calculate the current, same thing over here. And we are done. We now know current through each resistor. But do you understand, that's wrong.

WebbSince P = E / t, we see that. E = Pt. is the energy used by a device using power P for a time interval t. For example, the more lightbulbs burning, the greater P used; the longer they are on, the greater t is. The energy unit on electric bills is the kilowatt-hour (kW ⋅ h), consistent with the relationship E = Pt.
