Ohm's law states that the voltage within an electrical circuit is equal to the product of the current and the voltage. Mathematically it is written as V=IR where V is the voltage, I is the current and R is the resistance. If a circuit has a voltage of 9.0 Volts and a resistance of 36.0 Ohms, the current is I = V / R = 9.0/36.0 = 0.25 Amps.
It is useful to use a model in order to demonstrate how an electric circuit works.
<h3>What is a model?</h3>
In science, a model is a graphical representation that my result useful to predict the behavior of the components of a given system that works together to produce a particular outcome.
For example, an electrical circuit can be modeled by taking into account resistance, voltage, and intensity as parameters of functioning.
The electrical circuits are graphically represented by modeling the movement or flow of negatively charged electrons (e-) from the negative pole to the positive pole of a closed electric circuit.
In conclusion, it is useful to use a model (ie., a scientific model) to demonstrate how an electric circuit works.

Answer:
Pitch. The sound an article makes changes relying upon how quick it is vibrating. At the point when an item vibrates rapidly, sharp sounds are heard. Low-pitched sounds come from things that vibrate all the more gradually.
