What does cause resistance in electrical wires?
electrical resistence is occur in conductor due to over flow of current,in conductorAnswerResistance is not due to the 'flow of current'. It exists whether current is flowing or not! Resistance is determined by the type of material and its physical dimensions. Resistance depends upon the resistivity (which is also affected by temperature) of the material, and the length and cross-sectional area of that material.
How do you ground home recording system?
If you are getting a humming noise then you probably have an earth loop. This is where the resistance from one piece of equipment has a higher resistance than on other piece that it is connected to. The current flows through the lower resistance piece of equipment back to the earth on the mains causing the hum. There are two ways to cure this. the method used by recording studios is to create a star Earth. This is where all the earths from all devices comes back to a central earth point then to the mains earth. The alternative method is to break the shield at one end on the patch lead that goes from each device to interrupt the mains loop and force the earth current to run back down the mains cable earth.
What happens to the total resistance of a series circuit when another resistor is added?
Simply put, the purpose of a resistor is to 'resist' the flow of current. Ohm's Law tells us that for a given voltage, the larger the resistance, or value of that resistor, the lower the current that will flow. Ohm's Law states that I (current) = E (voltage) / R (resistance) - where current is measured in amps, voltage is measured in volts and resistance is measured in ohms.
What happens to the overall resistance of a circuit when too many appliances are connected across a 120 V outlet?
This is a very technical electrical question that may be difficult to understand without further study. But adding appliances to an outlet is the same as adding resistance in parallel. Adding resistance in parallel, the resistance of the circuit goes down. That is why you get more current flow. By contrast, adding resistance in series increases the resistance of the circuit and therefore reduces current, all else being equal.
What is the function of a earth wire?
The earth wire connects the metal frame of the electrical appliances to the ground. The convention is to have green colour for earth wires. The purpose of earthing is that in case of an insulation failure in some appliance, this wire connected to the metal body will provide a path for the current to flow on the ground. In absence of earth wire, this fault current would have flown through the body of the operator, causing electrical shock.
What is the ability of substance to slow down the electricity?
The property of a substance enabling it to slow down electricity is called resistance and is measured in ohms. This ability is called electrical resistance. Every substance has this. Gold has the minimum resistance for electricity. Such substance is called electrical conductor. And there are substance where the electrical resistance is affected by heat, light and other conditions. And for those substance where electricity can not flow are called electrical insulators (non-conductors) such as wood and ceramics.
What is the path that an electrical current travels?
electric current
Grouping of nerves that bring electrical impule down from the top half of the heart to the lower half of the heart?
The electrical impulse travels down bundles of His fibres, then down to the PURKINJE fibres.
How does lighting arrester working?
A lightning arrester (or lightning rod) works by providing a low resistance path to earth. This directs a lightning strike down the side of a building instead of it spreading through the electrical system.
On Earth which forces tend to slow an object down?
Air resistance, Gravity, Friction and Water resistance(Water and Air resistance depending if it's in air or water)
What is the name of the property of a material that slows down current and converts electrical energy into other forms of energy?
Resistance. And it doesn't "slow down current", it reduces the current.
Why it is important for satellites be outside the earth's atmosphere?
Air resistance. if in air they would slow down and fall.
Why is heater blower on citroen dispatch intermitent?
Check the back of the heater switch. The electrical plug may be having an melt down from resistance.
What is fault resistance?
Not all 'short circuits' are 'dead-shorts' -i.e. the resistance between the two conductors (or a conductor and earth) is not necessarily zero ohms -especially when the insulation between them has not completely broken down. The actual resistance is called the 'fault resistance'.
Which two forces cause a baseball hit with a baseball bat to fall down to earth?
Gravity and wind resistance.
What is the importance of wind energy?
The importance of Wind Energy is that it cuts down on Electrical Energy, which pollutes the Earth
Why did the feather and the hammer land the same time on the moon and different times on the earth?
The Earth has an atmosphere and the moon doesn't, so a falling feather on Earth runs into quite a bit of air resistance which slows it down much more than a hammer. On the moon, there is no air resistance.
