What is resistance expressed in?
Electrical resistance is measured in Ohms.
Is high electrical resistance good or bad?
electrical resistance is when something resists the electrical current .. eg rubber hope it helped
What symbol is often used for electrical resistance?
I have never come across a symbol for an electrical resistance box. As the resistance box is a test instrument and it would not be drawn on any electrical schematic there may not be a symbol designated for it. The last letter of the Greek alphabet is (Ω omega) and it is used for the electrical symbol for resistance.
What is meant by the resistance of an electrical component?
Think of it like this: Friction causes you difficulty in pulling heavy objects on a carpet. This frictional force is similar to electrical resistance. It is one of two ways to define how easily electricity will travel through an electrical element.
What is resistance welding?
Arc. It's where electrical resistance is used to create the heat for the welding process.
What is importance for making correct splice?
electrical splice? Good splice will allow current to flow without creating excessive resistance and heat
What measures electrical resistance?
an ohm meter OR multimeter is used to measure the electrical resistance...
What is the opposition to the flow of electrons is called?
Resistance, or electrical resistanceResistance, or electrical resistanceResistance, or electrical resistanceResistance, or electrical resistance
Why does your 04 Toyota road runner keep blowing alternators?
Spike in electrical system look for loose ground wire or loose connection that is building excessive resistance (heat)
Who when and how was electrical resistance discovered?
electrical resistance was discovered by Georg Ohm in the late 1820's.
What is resistance expressed in?
Electrical resistance is measured in Ohms.
What may cause an electrical conductor to heat up?
An electrical conductor may heat up due to excessive current passing through it, which increases its resistance and generates heat. Poor connections, overloading, or inadequate conductor size can also cause heating. This can lead to a potential fire hazard if not addressed.
What type of resistance do conductors have?
Conductors have a (low) Electrical resistance.
What is the name of an instrument used to vary electrical resistance?
Rheostat is the name of an instrument used to vary electrical resistance.
What is the electrical resistance of dirt?
I believe from Carson's equations that the electrical resistance of dirt isrd = 0.09530 Ohms / mile
What checks should be done to an electrical measuring device before attempting to measure electrical resistance?
Some of the checks that can be done to an electrical device before checking electrical resistance include the proximity of other magnetic fields and other electrical circuits. Measure electrical resistance while at a safe distance from strong electrical circuits.
Compared to thin wires electrical resistance in thick wires are?
The electrical resistance in thick wires is less than thin.
