For the circuit in the figure below, find the following. (Take  = 5.9 V,R = 5.5 Ω, and r = 1.4 Ω.)

(a) the magnitude of the current and the direction of positive current

(b) the potential difference across the battery terminals a and b

(c) the rate at which heat is being produced in the 5.5 Ω resistor

(d) the rate at which heat is being produced inside the battery

(e) the rate at which the battery's chemical energy is being used

Expert Solution
Step 1

Given:

Potential difference = 5.9 V

Resistance = 5.5Ω

Internal resistance = 1.4 Ω

Total resistance = 5.5 +1.4 = 6.9 Ω
