The copper is a conductor and the rubber is an insulator. Conductors allow electricity to be transmitted freely while insulators prevent most of the current from transmitting. The outer electrons of the conductor's atoms are not very stable and are able to freely move around the material. In a material such as copper, the valence electrons are essentially free and strongly repel each other. The atoms of insulators such as rubber, hold tight to their outer electrons which prevents electricity from flowing freely through.
If the Sun disappeared suddenly, we wouldn't know about it for about 8 minutes ... that's how long it takes for heat and light from the Sun to get here to Earth.
8 minutes after the Sun disappeared, the sky would turn totally black. All plants would immediately stop growing ... including all the plants that people or animals eat to live.
Then, after a few more minutes, we would start to notice that it was beginning to slowly get cooler, and that would continue until Earth was too cold for anything to live on it.
Answer:
Electric field will remain same.
Explanation:
Given that
At initial condition ,charge q = +3μ C
Electric field E = 4106 N/c
As we know that
Electric field due to charge q
Now when charge is replaced by new charge q'= -3μ C
From the expression of electric field we can say that electric field will remain same from same quantity of electric charge.
So we can say that electric field will remain same.
Answer:
a. Load.
b. Fuse.
c. Source.
d. Wire.
e. Switch.
Explanation:
An electric circuit can be defined as an interconnection of electrical components which creates a path for the flow of electric charge (electrons) due to a driving voltage.
Generally, an electric circuit consists of electrical components such as resistors, capacitors, battery, transistors, switches, inductors, fuse, etc.
Matching the given circuit parts to their appropriate functions, we have;
a. Load: an appliance or device that uses electricity source like bulbs, computers, television, radio, etc.
b. Fuse: it is a safety device made from materials that easily melt even before the wires carry too much current.
c. Source: it is where electricity came from like batteries and generators.
d. Wire: it is the pathway of electricity from the resources (source) to the load.
e. Switch: it controls the flow of electricity from the source. It is typically used to turn ON or turn OFF a load.
