What is electrical energy converted to inside a toaster?

Figure E25.47 1.0.2 12.0 V wti 25.47 . In the circuit in Fig. E25.47, find (a) the rate of conversion of internal (chemical) energy to electrical energy within the battery; (b) the rate of dissi- pation of electrical energy in the battery; ©) the rate of dissipation of electrical energy in the external resistor.
