A child's electronic toy is supplied by three 1.58 V alkaline cells having internal resistances of 0.0210 0 in series with a 1.53 V carbon-zinc dry cell having a 0.190 Q internal resistance. The load resistance is 15.0 0.
(a) Draw a circuit diagram of the toy and its batteries.
(b) What current (in A) flows?
(c) How much power (in W) is supplied to the load?
(d) What is the internal resistance (in 0) of the dry cell if it goes bad, resulting in only 0.500 w being supplied to the load?
