When an electric current passes through a wire, heat energy is produced. The thermometer reading indicates how much heat energy, H, has been produced. The table below shows the values of H, for different currents, I. Current, I (A) 0 Heat energy, H (J) 0 1² 0.50 1.0 1.5 2.0 2.5 3.0 140 600 1400 2500 3800 5500 a. Does the electric current depend upon the heat energy or does the heat energy depend upon the current? Hence write down the dependent variable.

Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
