* Only need help on c,d and e!
For the circuit in the figure below, find the following.(Take R = 5.8, r = 1.1.) (a) the magnitude of the current and thedirection of positive current magnitude 1 A direction 2---Select---clockwise direction around thecircuitcounterclockwise direction around thecircuit
(b) the potential difference across the battery terminals a andb
3 V

(c) the rate at which heat is being produced in the 5.8 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 1 A direction 2---Select---clockwise direction around thecircuitcounterclockwise direction around thecircuit

Explanation / Answer

Since the resistors are in series, the current you found in(a) applies to both resistors equally, because the current mustflow through the wire somehow! (c): Use the equation P = i2r, where P is thepower dissipated by a resistor, i is the current through theresistor, and r is the resistance. So, for a resistance of5.8, P = (0.84057)2*5.8 = 4.098 W (d): For the battery, the resistor's resistance is1.1, so P = (0.84057)2*1.1 = 0.777 W (e): Since energy is conserved, the total heat outputfrom the circuit will be equal to the energy being consumed in thebattery. So, 4.098 + 0.777 = 4.875 W I'm not sure how they want to you to treat significantfigures, so I'll leave the rounding up to you.
