Question

A battery has three cells connected in series, each with an internal resistance of 0.020-Ω and an emf of 1.50 V. This battery is connected to a 10.0-Ω resistor.
(a) Determine the voltage across the resistor.
(b) How much current is in each cell?
(c) What is the rate at which heat is generated in the battery and how does it compare to the Joule heating rate in the external resistor?
