A car battery with a 12 V emf and an internal resistance of 0.037 Ω is being charged with a current of 45 A. Note that in this p
matrenka [14]

Answer:

Part a)

V = 13.665 V

Part b)

P = 74.9 Watt

Part c)

P = 540 watt

Part d)

P_r = 0.878

Explanation:

Part a)

As we know that the during the charging process of the battery the terminal voltage of the cell is given as

V = E + iR

V = 12 + (0.037)(45)

V = 13.665 V

Part b)

Thermal energy dissipated in the battery is due to its internal resistance

so it is given as

P = i^2 R

here we have

P = 45^2 (0.037)

P = 74.9 Watt

Part c)

rate of energy conversion in the in the battery is given as

P = E. i

P = 12(45)

P = 540 watt

Part d)

percentage of the power conversion is given as

Pr = \frac{P_{out}}{P_{total}}

Pr = \frac{540}{540 + 74.9}

P_r = 0.878
