Given :
Reem took a wire of length 10 cm. Her friend Nain took a wire of 5 cm of the same material and thickness both of them connected with wires as shown in the circuit given in figure. The current flowing in both the circuits is the same.
To Find :
Will the heat produced in both the cases be equal.
Solution :
Heat released is given by :
H = i²Rt
Here, R is resistance and is given by :
![R = \dfrac{\rho L}{A}](https://tex.z-dn.net/?f=R%20%3D%20%5Cdfrac%7B%5Crho%20L%7D%7BA%7D)
So,
Now, in the question every thing is constant except for the length of the wire and from above equation heat is directly proportional to the length of the wire.
So, heat produced by Reem's wire is more than Nain one.
Hence, this is the required solution.
This causes the resistance to INCREASE and the current to DECREASE
Answer:
Yes, it is possible.
It is called humidity. The quantity is reduced as the temperature go down. That’s why it condenses in a fridge or in a air conditioner unit. To create vapor there is various ways such as heating (evaporation) or fogging of liquid water. It will stop when the vapor pressure is reached and it depends of the temperature. The vapor pressure of water is 101.32 kPa at 100°C, which is the atmospheric pressure at sea level. It means that at that pressure and that temperature and above the water is totally converted in gas in the boiling process.
Answer:
Short
Explanation:
A short circuit has basically no resistance.....kinda like just twisting the + and - wires together....sparks will fly !
