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
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 type of resistance do conductors have?
Conductors have a (low) Electrical resistance.
What is excessive electrical resistance?
High resistance means insulation
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.
Who is ohm?
Ohm is the SI unit of electrical impedance (AC) or the electrical resistance (DC), named after Georg Ohm. Not Ohms!
What is an obstruction of electrical flow?
Resistance.
