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 causes resistance in electrical circuits?
Resistance in electrical circuits is caused by the interaction of electrons with the atoms in a material, which slows down the flow of electric current. This resistance is measured in ohms and can be influenced by factors such as the material of the conductor, its length, and its cross-sectional area.
What slows an electrical current?
Factors that can slow down an electrical current include resistance in the conductor, length of the conductor, and presence of any insulating materials. Resistance converts electrical energy into heat, reducing the current flow. Longer conductors offer more resistance to the flow of electrons, which slows down the current. Insulating materials can also impede the flow of electrons in a circuit.
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.
What is the path that an electrical current travels?
electric current
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.
Where does earthing current go?
Earthing current flows through the earth to provide a safe path for electrical faults to return to the ground. This helps stabilize the electrical system and prevents the risk of electric shocks or fires by ensuring excess current does not flow through people or equipment.
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.
What is the purpose of a small step down transformer in electrical circuits?
A small step-down transformer in electrical circuits is used to reduce the voltage from a higher level to a lower level. This helps to safely power devices that require lower voltage levels, protecting them from potential damage.
Why it is important for satellites be outside the earth's atmosphere?
Air resistance. if in air they would slow down and fall.
On Earth which forces tend to slow an object down?
The main forces that tend to slow an object down on Earth are friction, air resistance, and gravity. Friction occurs when the object moves against a surface, air resistance is the drag force experienced as an object moves through the air, and gravity pulls the object downward.
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.
