CURRENT
This is the flow of electric charge through a conductor.
What is Electric Current?
This formula is used to calculate the resistance of a material based on its length, cross-sectional area, and resistivity.
What is R=V/I
This material property measures how strongly a substance opposes the flow of electric current, and is independent of its shape or size.
What is Resistivity?
This term describes materials that follow Ohm's Law, exhibiting a constant resistance regardless of changes in voltage or current.
What is ohmic?
The unit of measurement for electric current.
What is Ampere
It is measured in ohms (Ω) and depends on the material's properties, such as its length, cross-sectional area, and resistivity.
What is Resistance?
The unit of resistivity is expressed in ohm-meters
What is rho (ρ)?
Materials or components that do not follow Ohm's Law and exhibit a non-linear relationship between voltage and current are called this.
What is non-ohmic?
A circuit consists of a 12-volt battery and a resistor with a resistance of 4 ohms. calculate the current flowing through the circuit.
3 amperes
These conduct electricity by allowing the movement of electrons without transferring physical matter.
What are metallic conductors?
This formula expresses the relationship between resistivity, resistance, length, and cross-sectional area.
What is ρ=R•A/L
This German physicist is best known for developing a law that defines the relationship between voltage, current, and resistance in an electrical circuit.
Who is Georg Simon Ohm?
This term refers to the actual flow of electrons, which are negatively charged particles.
What is Electron Flow
This component is used in electronic circuits to limit the flow of electric current.
What is Resistor
This property measures how easily a material allows electric current to flow, and is the inverse of resistivity.
What is Conductivity
This 1827 work by Georg Simon Ohm mathematically analyzed the behavior of electrical circuits and introduced what is now known as Ohm's Law.
What is "Die galvanische Kette, mathematisch bearbeitet" (The Galvanic Circuit Investigated Mathematically)?
