Fire engines may be hooked up to the mains when parked, to use electrical heaters to keep the engines at operating temperatures which makes them run better from the start, and to let on-board chargers keep the batteries topped up. Some may even have built-in coolers for medical supplies.
Yes
keyboard can use both
because they have lots of stuff that use electricity . like , ladders that go in different directions , water pumps and sirens .
It varies in different countries round the world but most use 240 volt mains.
The steam engines required water, with coal or wood from the tender providing the fire to heat the boiler. The diesel engines require diesel fuel to operate, plus their lubricationa and cooling systems. The electric trains don't have engines, but use motors, operated by electricity.
Mains electricity is typically more reliable and provides a constant power source compared to batteries, which can run out of charge. Using mains electricity can also be more cost-effective and environmentally friendly in the long run, as it avoids the need for constantly replacing disposable batteries. Additionally, devices powered by mains electricity can often deliver more consistent performance than those relying on batteries.
A typical TV is powered by mains electricity. There are also 12 volt and battery versions for use in campers etc
well before electricity we had to use fire wood and that was our electricity thats all i really know
Most ovens do not use fire, they simply heat up the air with electricity.
The Fair Isle islanders do not use mains electricity because of their remote location and the high cost of connecting to the mainland grid. Instead, they rely on locally generated renewable energy sources like wind turbines and solar panels, along with backup diesel generators for when renewable sources are not sufficient.
Electricity supplies in the US contain about 19 percent nuclear generation, so anything which uses electricity from the mains uses nuclear power
because light bulbs use electricity ,and candles use fire, and electricity last longer
