Relationship help (physics wise that is ;)

Im trying to find a formula(s) that link current to resistance to the heat produced by the resistance, simaliar to a heating element only it would be a liquid or aqueous medium

Have a look at this thread;

Ah, that helps, I also came across R*I^2 =T, for future referance are these equivalent in some aspect, I am guessing this one has some limitation in regards to what materials it can be used for.

Also does someone on here have a good resource for specific heat tables?

The "Handbook" has these tables I think.

I can offer some insights on the relationship between current, resistance, and heat in a system involving a liquid or aqueous medium.

Firstly, we need to understand the basic principles of Ohm's Law, which states that the current flowing through a conductor is directly proportional to the voltage applied and inversely proportional to the resistance of the conductor. In other words, as the resistance increases, the current decreases, and vice versa.

In the case of a liquid or aqueous medium, the resistance can be affected by factors such as the concentration of ions, the temperature, and the type of liquid. Therefore, the resistance of the medium can vary and impact the amount of current flowing through it.

Now, when current flows through a conductor, it encounters resistance and produces heat due to the collisions between the moving electrons and the atoms in the conductor. This heat is known as Joule heat or resistive heat.

To calculate the heat produced by the resistance in a liquid or aqueous medium, we can use the formula:

Q = I^2 x R x t

Where Q is the heat produced (in joules), I is the current (in amperes), R is the resistance (in ohms), and t is the time (in seconds).

This formula shows that as the current increases, the heat produced also increases, but it is also affected by the resistance and the time for which the current flows.

Additionally, we can also use the formula:

Q = V x I x t

Where V is the voltage applied (in volts). This formula takes into account the relationship between voltage, current, and time to calculate the heat produced.

In conclusion, the relationship between current, resistance, and heat in a system involving a liquid or aqueous medium is complex and can be affected by various factors. The two formulas provided can help in understanding and calculating the heat produced in such a system. However, further experimentation and analysis may be required to determine a more precise and comprehensive formula for this relationship.
