An electric toaster has a resistance of 12 Ω.
Ohm’s law states that the voltage is proportional to the resistance times the current or V=IR. Power dissipated by an electrical component found by multiplying the current times the voltage or P=VI
the strength of electric and magnetic forces Students will understand the electrical quantities of and the relationship between current, voltage, and resistance in order to understand Ohm’s Law. Calculate the electric current, voltage and resistance of basic electric circuits. Objectives: NATIONAL ELECTRONICS MUSEUM
The electrical resistance of a resistor is measured inohms. The symbol for an ohm is the greek capital-omega: Ω. The (somewhat roundabout) definition of 1Ω is the resistance between two points where 1 volt (1V) of applied potential energy will push 1 ampere (1A) of current.
Electrical resistance is the repulsion of a current within a circuit. It explains the relationship between voltage (amount of electrical pressure) and the current (flow of electricity). Resistance, discovered by Georg Simon Ohm in 1827, is the ratio between voltage and current.
