What is the name of the electrical pressure that causes current to flow in a circuit?
Electrical pressure is called "electro-motive force" (EMF). It is measured in volts. Pressure and the quantity of electricity transmitted can be considered analogous to pressure and quantity of water flowing in pipes: the longer the distance, the higher is the pressure (called the "voltage" for electricity) that is necessary to pump the flow of water (called the "flow of electrical charge, which is also known as the "electric current"). That is why, for long distance transmission, high pressure (voltage for electricity) is required, failing which, the current - and therefore the power - will not reach the intended destination. Instead, it will be lost (also called "dissipate") along the way. We can think of electrical current as the quantity of electricity which will be drawn from the pipeline (= cables for electricity) at the pressure (= voltage) required.
What did the photophone do?
I think it used only light to transmit messages instead of electricity... I could be wrong though you may want to try wikipedia
Are humans good conductors?
good enough to conduct electricity in a fatal way yes! if you arebeing electricuted and you touch someone who is un earthed then they get instead - or at least the worst of it.
How far does electricity travel in 7 milliseconds?
So for a typical AC current in a typical lamp cord, the electrons don't actually "flow," instead they vibrate back and forth by about a hundred-thousandth of an inch.
Why do all streams disappear in bhabar belt?
As you might already know, the Bhabar belt has pebble deposits. So, doesnt that make it Highly porous! so instead of the stream flowing above it it will flow below the top layer of pebbles n that makes it disapper! hope this helps!
What safety device ensures that electricity will flow through it when flowing downhill instead if through people?
Ground wires
A charge that stays on an object instead of flowing in a current?
static electricity
What is the unit of electricity current flow?
The unit quantity of electricity is the Coulomb. The rate of electricity flow in coulombs per second is the Ampere, sometimes shortened to Amp. Note: current doesn't flow, instead current itself is a flow rate (flow of coulombs of charge per second.) When coulombs are flowing, the flow rate is measured in amperes.
Why are electric wires made out of metal instead of rubber?
Electric wires are made out of metal, typically copper or aluminum, because metals are good conductors of electricity. Rubber is an insulator, which means it does not allow electricity to flow through it easily. Using metal wires ensures efficient transmission of electricity while minimizing energy loss due to resistance.
Will a light bulb evaporate water?
If you were to put a bare wire belonging to anything in a glass of water, the electricity flowing through the wire would have no reason to continue to travel through the wire instead of dispersing in the water. The water offers less resistance, so the electricity flows through that instead of the wire. This is known as creating a short circuit, or a short, for short! With no electricity flowing through the bulb, it will turn off.
What way should your right front wheel be facing when you are parked on a downhill curb?
In a downhill area, you should always park with the front wheels toward the curb. The theory is that if the brakes malfunction, the car will move towards the curb and stop, instead of going downhill, gathering speed and causing an accident.
Which landform was not created by flowing water?
Volcanoes are a landform that is not created by flowing water. Instead, they are formed by the accumulation of lava and volcanic materials from the Earth's interior.
How is cross-country skiing different from down hill skiing?
Quite a bit is different. The gear is different, the skis are straight, as opposed to downhill skis being curved (the curve makes it easier to turn on a downhill slope), the boots in cross country are not stationary in the bindings, as downhill boots are, instead you can move the heels, and the poles used in cross country are longer. Also, the slopes are not nearly as steep as in downhill skiing.
What is a charge that stay on an object instead of flowing in a current?
A charge that does not move is called a static charge.
Can uranium be used instead of electricity?
Uranium is used in nuclear power reactors to produce electricity or thermal energy.
Meltwater is a film of water that forms?
Melt ponds are formed when meltwater pools on the surface instead of flowing.
Is coal iron and steel the most important industry in the world?
No, coal produces electricity, so electricity is instead of coal
