The temperature is the degree on intensity of heat in a specific place. Usually, the temperature of thermic neutrality is 70 Fahrenheit or 21 Celsius.
Hope this Helps! :)
Produced the model is the resistance of the circuits decreased as a battery voltage increased (option-B).
<h3>What connection does there exist between voltage and current, current and resistance, and voltage and resistance?</h3>
Ohm's Law describes how current, voltage, and resistance are related to one another. According to this, as long as the temperature doesn't change, the current flowing through a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
The more work a certain quantity of electrons can accomplish at a given voltage. The quantity of electrons that are presently moving through any one point in a circuit at any particular time is known as the current. At the same voltage, a larger current can perform more work. Current times voltage equals power.

Protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge).
Answer: A changing magnetic flux establishes a current in a circuit.
Faraday's Law of Electromagnetic Induction was formulated from the experiments made by him and states that:
<em>The voltage induced in a closed circuit is directly proportional to the speed with which the magnetic flux that crosses any surface with the circuit as edge changes in time</em>
where:
is the Electric Field
is the infinitesimal element of the C contour
is the magnetic field density
is an arbitrary surface, whose edge is C
The negative sign indicates the direction of the induced current and refers to the opposition between the fields induced by the magnetic flux and the electromotive force.
So, it is the change in the magnetic flux that establishes a voltage in the circuit, hence current.
