Question #1488

In 1994, a prototype of what was claimed to be the first "practical" electric car was introduced. Recharging the batteries is not very practical, though. Calculate the average time needed to recharge the car's batteries if a 13.6 A current carries 4.40 x 10^5 C to the batteries.

Expert's answer

The time needed to recharge the batteries is

t = Q/I = 4.4x105[C]/13.6[A] = 32.353 x 103 s = 8.99 h.

t = Q/I = 4.4x105[C]/13.6[A] = 32.353 x 103 s = 8.99 h.
