Question

R = 5.7 , r = 1.1 .) (a) the magnitude of the current and the direction of positivecurrent magnitude A direction ---Select---clockwise direction around the circuitcounterclockwise direction around thecircuit
(b) the potential difference across the battery terminals a andb
V

(c) the rate at which heat is being produced inthe 5.7 resistor
W

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

(e) the rate at which the battery's chemical energy is beingused
W magnitude A direction ---Select---clockwise direction around the circuitcounterclockwise direction around thecircuit

Explanation / Answer

(a) the magnitude of the current and the direction of positivecurrent I=5.4/(5.7+1.1)=0.794A, Clockwise (b)(b) the potential difference across the battery terminals aand b U=I*5.7=4.526V (c)(c) the rate at which heat is being produced inthe 5.7 resistor P=I2*5.7=3.59 W (d)the rate at which heat is being produced inside thebattery p=I2*1.1=0.69 W (e) the rate at which the battery's chemical energy isbeing used P=E*I=4.288W
