They are a source of electrial energy because you have to charge them and people tend to chanrge them longer than needed suck as, overnight.

Define voltage in terms of electric potential energy and charge?
When unlike charges are moved farther apart, they gain electrical potential energy. Electrical potential difference is the change in potential energy per coulomb of charge. Voltage is the common name for electrical potential difference and is measured in volts (V). Electrical energy depends on the amount of charge and voltage. Electrochemical cells, or batteries, are a common source of voltage. We use voltmeters to measure potential difference. :)
Transformation of electrical energy to sound energy?
Electrical to kinetic to electrical energy in your cells
Why does energy increase when voltage increases?
If we increase the voltage by adding extra cells or batteries we give the electrical charges more energy and so, the current flowing around the circuit increases.
What changes light to electrical energy?
solar cells are used to change light energy into electrical energy
What Machine Changes energy of motion into electrical energy?
Solar Cells
How can you define batteries?
A container consisting in one or more cells, in which chemical energy is converted to electrical power and is used as a source of power.
Where is the store of electrical energy in a circuit?
Capacitors, inductors, and batteries all store electrical energy.
How do you make electricty?
Several ways. Mechanical Energy to Electrical Energy: Generators and Alternators Chemical Energy to Electrical Energy: Batteries Fuel Cells Thermal Energy to Electrical Energy: Thermocouples
Can photovoltaic cells store energy?
no, photovoltaic cells just produce the electricity. the electrical energy produced from the cells will be stored in storage systems (Batteries)
What is an advantage of fuel cells over lead storage batteries?
Electrical energy is continuously obtained.
5 examples of electrical energy?
examples of electrical energy can be lightning,toastor,hairdryer,powercode and batteries.
What kind of electrical energy does a calculator use?
most calculators are powered by solar energy but some are powered by batteries

How do solar cells store energy?
When we say "solar cell", we're talking about the flat panel with a shiny blue surface that the sun shines on and generates electricity. That's the "solar cell" part, and it only produces the electrical energy -- it doesn't store it. That panel of cells is always wired to a set of storage batteries somewhere inside. (In some places, this set of batteries is called the "accumulator".) The cells convert solar energy to electrical energy during daylight hours, and the batteries store whatever isn't immediately used, making it available at night.
What is the scientific name of batteries?
Galvanic cell, voltaic cell, electrochemical cell. Do not confuse it with electrolytic cell.
Why does energy increase when voltage increases?
If we increase the voltage by adding extra cells or batteries we give the electrical charges more energy and so, the current flowing around the circuit increases.
