' J ' means Joules , unit for the amount of Energy in Physical Science... Heating Effect of Current ...
Joule's Constant = Electrical Energy in Joules / Amount of Heat in calories
Electrical Energy in Joules = Voltage in volts x Current in amperes x Time in seconds
Amount of Heat in calories = Mass of Water x Specific Heat of Water x Change in Temperature of Water + Mass of Calorimeter x Specific Heat of Calorimeter x Change in Temperature of Calorimeter
ANSWER: The Amount of Heat will be very hot and Joule's Constant will be too big which will make it not realistic as part of the experimental calculations.
You must know that it is necessary to get the temperature in the state of equilibrium. Remember that, due to the use of the metal stirrer which absorbed the heat energy, the temperature of water inside the calorimeter had decreased partially or was delayed in rising up despite to the fact that the electrical energy generated is proportionally equal to the increase in temperature of the calorimeter.

What is the working principle of Magnetic stirrer?
A magnetic stirrer is helpful for dissolving solids in liquids. As there are several different appearances, all of them will at least have a base with a speed-controlled spinning magnet inside and an exterior stirring bar. You place the stirring bar into a flask or beaker by tenderly sliding it beside the wall of the container. To avert fracture, don't drop the bar onto the bottom of the container. Place the container on the stirrer base and turn the speed control knob to its lowest set. Use enough speed to start the bar turning in the container. If using exact volumes, as with a volumetric flask, be sure take the measurements before adding the stirring bar.When stirring is finished, keep the stirring bar in the container by draft the liquid into another container. Carefully wash the original container and the stirring bar.
What are the use of a calorimeter?
A calorimeter is a device used for calorimetry, the science of measuring the heat of chemical reactions or physical changes as well as heat capacity. The word calorimeter is derived from the Latin word calore, meaning heat. Differential scanning calorimeters, isothermal microcalorimeters, titration calorimeters and accelerated rate calorimeters are among the most common types. A simple calorimeter just consists of a thermometer attached to a metal container full of water suspended above a combustion chamber.
What is the difference between apparatus and equipment?
apparatus are non machines used in a Lab. It may be a beaker, conical flask, test tube etc...but equipment is a machine which runs on electricity like disintegrator machine, friabalator, stirrer etc...

Can you make a back scratcher from a paint stirrer?
An effect back scratcher can be made from a paint stirrer in three ways. 1. Scratch your back with the stirrer without changing it in any way. 2. Attach a soft scratcher (such as a scrubby) to the stirrer. 3. Carve the end of the stirrer into a usable shape.
