What measures electrical resistance?
an ohm meter OR multimeter is used to measure the electrical resistance...
Who when and how was electrical resistance discovered?
electrical resistance was discovered by Georg Ohm in the late 1820's.
What are the units of resistance in an electrical circuit measured in?
The units of resistance in an electrical circuit are measured in ohms ().
What is resistance expressed in?
Electrical resistance is measured in Ohms.
What component in an electrical circuit provides resistance?
The component in an electrical circuit that provides resistance is called a resistor.
What is the opposition to the flow of electrons is called?
Resistance, or electrical resistanceResistance, or electrical resistanceResistance, or electrical resistanceResistance, or electrical resistance
What is the formula for calculating the resistance in an electrical circuit?
The formula for calculating resistance in an electrical circuit is R V/I, where R is the resistance, V is the voltage, and I is the current.
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 excessive electrical resistance?
High resistance means insulation
How do you ohm out a wire to test its electrical resistance?
To ohm out a wire and test its electrical resistance, you need a multimeter. Set the multimeter to the resistance (ohms) setting. Connect the multimeter's probes to each end of the wire. The multimeter will display the resistance value in ohms, indicating the wire's electrical resistance.
What is the relationship between resistance and temperature in electrical circuits?
In electrical circuits, the resistance of a material typically increases as its temperature rises. This relationship is known as temperature coefficient of resistance.
What is the formula for electrical resistance?
Resistance(Ohms)= Voltage(volts)/Current (Ampheres) -X
