The electrical resistance of a penny can vary based on its composition and condition, but a typical copper penny (post-1982) has a resistance of about 1 to 2 ohms. This value can change due to factors like oxidation, surface condition, and temperature. Generally, the resistance is low due to copper's excellent conductivity.
What else can I help you with?
What is resistance expressed in?
Electrical resistance is measured in Ohms.
What is excessive electrical resistance?
High resistance means insulation
Is high electrical resistance good or bad?
electrical resistance is when something resists the electrical current .. eg rubber hope it helped
What is the measurement of electrical resistance called?
The measurement of electrical resistance is called ohms, symbolized by the Greek letter omega (Ω). It quantifies how much a material opposes the flow of electric current. The higher the resistance, the more difficult it is for current to pass through. Ohm's Law relates voltage, current, and resistance in an electrical circuit.
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 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 will drop faster the penny or the feather?
The penny will drop faster than the feather due to the difference in mass and air resistance. The feather experiences more air resistance, which slows down its fall compared to the penny.
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 excessive electrical resistance?
High resistance means insulation
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 is the name of an instrument used to vary electrical resistance?
Rheostat is the name of an instrument used to vary electrical resistance.
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.
