Explain why an electric bulb becomes dim when an electric heater in parallel circuit is made onWhy dimness decreases after some time?
this happen due to sudden amount of voltage drop in the main feeder due to large current drawn by the heater , so this drop in voltage will let the bulb operate by avltage of a mount (V-Vd) [where V represent the supply voltage and Vd represent the voltage drop in the main feeder of the circuit] , which is less than the voltage before the heater is connected and due to this situation the current passes through the wire of the bulb will be less and therefore the brightness of the bulb becomes dim.after a while the wire of the heater will has high temperature which increase its resistance and due to this the current drawn by the heater will decrease than the current at the first time , therefore the drop in voltage will also decrease , which implise increase in current drawn by the bulb and therefore the dimness decrease .

What happens when the emitter bypass capacitor is shorted?
Then gain becomes equal to hFe and thermal runaway becomes a problem. Further, the reduction of gain as frequency decreases is eliminated, so the stage's operation as a high pass filter is compromised.
If a parallel circuit shorts at the battery will the entire circuit short out too?
If at battery,parallel circuit shorts then equivalent resistance of circuit becomes approximately 0 Ohms,and therefore as current follows low resistance path infinite amount of current due to low resistance will flow through the wire so,entire parallel circuit will short out,but wire will burn and battery may get damaged.

Why induced emf alternates?
Here is A Simple answer for this question as you know that emf is induced in the conductor when there is change of flux linkage to the conductor which gives rise to the inducement of electric field in the conductor that provide drift velocity to the electrons hence emf is induced in the conductor but the last only till the change in flux in progress and becomes zero as soon as the flux linkages becomes constant hence we summaraize that for inducement of current there must be change in change of flux hence change in electric field that gives rise to allternating emf.
What does this sentence mean fuses are the police officers of electric current?
Fuses protect an electrical circuit. When current in an electrical circuit becomes dangerously high the fuse will open protecting people and property. Police men/women protect people and property from the dregs of society.
Which ways can one avoid water heater problems, and are there any ways to trouble shoot electric heaters?
In order to ensure that your electric water heater stays in good working order, you should regularly check for, or if unable to do yourself, have a maintenance person check for any damage or faulty wiring. Regularly inspecting the electrical connections, and piping can allow you to catch any deterioration or wear before it becomes a large problem.

The strength of the electric field of a charged particle becomes greater as the distance from the particle increases.?
No, the strength of the electric field of a charged particle becomes weaker as the distance from the particle increases. The electric field strength follows an inverse square law relationship with distance, meaning it decreases as the distance from the charged particle increases.
How does the electric force between two charged objects change when the distance between the objects decreases?
Less distance --> more force.
The strength of the electric field of a charged particle becomes greater as the distance from the particle decreases?
Yes, the strength of the electric field of a charged particle does increase as you move closer to the charged particle. This is because electric fields follow an inverse square law, meaning that the field strength is inversely proportional to the square of the distance from the charged particle. As you move closer, the distance decreases, leading to an increase in the electric field strength.
How does distance affect the strength of an electric field?
The strength of an electric field decreases with distance. As you move farther away from a charged object, the electric field intensity becomes weaker. This relationship follows an inverse square law, meaning that the electric field strength is inversely proportional to the square of the distance from the charged object.
How are two parallel plates charged with electricity and what effect does this have on the electric field between them?
When two parallel plates are charged with electricity, one plate is positively charged and the other is negatively charged. This creates an electric field between the plates, with the positive charges attracting negative charges and vice versa. The electric field between the plates becomes stronger as the magnitude of the charges on the plates increases.

Describe how the electric resistance of a wire changes as the wire becomes longer. How does the resistance change as the wire becomes thicker?
As the wire becomes longer, its resistance increases because there is more material for the electrons to travel through. On the other hand, as the wire becomes thicker, its resistance decreases because there is more space for the electrons to flow, reducing the collisions with the wire material and therefore lowering the resistance.
