-- the current in the arc -- your definition of 'intensity'
Because its exact name is "current intensity". The letter "i" comes from intensity.
The amount of current produced in a photocell depends on the intensity of light that hits the cell. Higher light intensity will generate more current, while lower light intensity will generate less current. The current produced is generally in the range of microamps to milliamps.
How hard you work during exercise
the intensity of desire or enjoyment
The vividness or dullness of a color
because current was originally reffered to as electrical intensity.
The unit of current intensity is the ampere (A), which is defined as the flow of one coulomb of charge per second in a circuit.
Intensity.
An ammeter is a tool used to measure the intensity of electric current flowing through a circuit. It is connected in series with the circuit and provides a reading in amperes (A) to indicate the amount of current passing through the circuit at a given moment.
As the intensity of a circuit increases, the voltage or resistance also tends to increase. According to Ohm's Law (I = V/R), when voltage or resistance increases, the current in the circuit also increases. Therefore, current increases with increasing intensity as a result of the relationship between voltage, resistance, and current in the circuit.
