Moving water (dams, rivers, tides) and turbines (like an electric motor in reverse) that will produce electricity when the moving water spins them round.
A Light bulb lights in a complete circuit because then the electricity from the battery can travel round the wire that has no breaks. BUT the switch has to be close. Z
When an incandescent light bulb (the normal round ones that Thomas Edison invented) is placed into a "hot" circuit, (meaning there is electricity flowing through it), the electricity passes through the filament (little metal wires) on the inside. As the electricity passes through it, the wires heat up and make a chemical reaction causing light to be emitted.
round 1.998 to the four decimals as needed = 1.9980
A toslink cable has a round connector that provides digital audio data using small pulses of light instead of electricity. It is manufactured by Toshiba.
For it to meaningfully to be a circuit, electrons must flow round the complete circuit. Thus a source of energy is needed, be it a battery, or the mains electricity.
Usually it works the other way round.
For the circuit to be connected all the way round because if there are breaks in the circuit the electricity will not flow back round. and number 2 a battery or a power source because without power where is the electricity coming from to be honest. Hope it helped. Thanks. xx
