Overloaded curcuits are when gou have to many items running at one time (to much power on one cicuit) to prevent it simply turn some of the items on the circuit off or change a fuse to one that can handle the load if the power is to much the circuit breaker will open cutting off the power.
Reactants is a starting substance in a chemical reaction; (reactants appear on the left-hand side of a chemical equation).
Products is a substance produced in a chemical reaction; (products appear on the right-hand side of a chemical equation).
Limiting reactant is the reactant that has the smallest stoichiometric amount in a reactant mixture and consequently limits the amount of product in a chemical reaction.
Answer:
a) Slow down
b) Decreasing.
Explanation:
a) The energy that is converted to heat can be written as:
As the resistance increases, with constant voltage, the amount of power dissipated as heat decreases (less current trought the resistor).
Then, we can conclude that, as the energy dissipated by the resistor is less as its resistance is increased, the heating process will slow down.
b) We have to evaluate what happens with the resistivity of the resistor during the heating.
We know that resistivity of a nichrome wire increases with the temperature. With the conclusion of the previous question, if the resistivity increases and the voltage stays constant, the current in the circuit will decrease as the resistor became hotter.
We can conclude this using the Ohm's law:
