All of the electric charge in the batteries comes originally from the energy in the fuel. true or false?
Homework Answers
FALSE
The electric charge in the batteries comes originally from the chemicals. The battery is a device that converts chemical energy into electricity which is used to run our power & energy needs. This charge does not come from fuel energy, rather is a result of chemicals and electrolyte along with positive & negative charge rods present in the battery.

A lightweight electric car is powered by a series combination of ten 12.0-V batteries, each having negligible internal resistance. Each battery can deliver a charge of 154 A · h before needing to be recharged. At a speed of 82 km/h, the average frictional force due to air drag and rolling friction is 1.34 kN. (a) What must be the minimum power delivered by the electric motor if the car is to travel at a speed of 82 km/h? ________kW...

2. Aluminium-air batteries produce electricity from the reaction of oxygen in the air with aluminium. They have the highest energy densities of all batteries, and an electric vehicle with aluminium batteries has the potential for up to eight times the range of a lithium-ion battery with a significantly lower total weight. However, they are not widely used because of problems with high anode cost and...
