Capacitors

Capacitors

Capacitor is a device that is normally used in electrical appliances such as radios, computers and TV.

There are many different types(looks) of capacitors as shown below:

Image result for designs of capacitors

The function of the capacitor is to store electrical charges. Remember , we have 2 types of charges ( positive and negative). Once the capacitor has stored the charge, it can release electrical energy.

I give you an example:

The flash unit of camera also uses a capacitor. The fact that the camera can give out the flash, it is actually releasing the energy from the charge that is stored in the capacitor.

When we measure something , it must has its own quantity and unit. For example,
(i) the length (quantity) of a ruler --> the unit is metre
(ii) the mass (quantity) of a ball --> the unit is kg

 Same goes to the capacitor, the quantity measured by the capacitor is capacitance and its unit is Farad. Scientifically, the meaning of capacitance is the ratio of the amount of  charge to the potential difference across the capacitor plates. C= Q/V

In a simple sentence, the capacitance is actually a measure of how good a capacitor can store charge. The higher the value of capacitance of a capacitor , the higher the ability of the capacitor to store charge.

Magnetic Field

Magnetic Field, B To define Magnetic field, we start with the word field. Field means a region or space. The magnetic field is defined as a region where the magnetic force can be felt. In other words, a force (repel/attract) can be felt in the region. Bar Magnet We will find that 2 North(N) poles will repel if we bring the poles of two bar magnets together. Same goes to that of 2 South(S) poles. However North and South pole attracts. The strength and direction of the field are represented by lines. Knowing that, the direction of magnetic field is from North to South. Magnetic field is able to be detected by 1) Compass (have been used over 2000 years 2) Hall Probe Applications: Swipe cards, Video tapes & Computer discs -use magnetism to store information. History: In 1819, Hans Christian Oersted noticed that a compass needle was deflected by an electric current in a nearby wire. Remember!! the compass is used to detect any existance of magnetic field.

Root Mean Square Current (I rms)

Root Mean Square Current As mentioned in the previous post , the value of AC is always changing. Then, how do we measure its value??? We could not use the maximum value of the current Io, because it only occurs at a moment. The average current is ZERO . Hence, one effective value that we could use the root mean square value. Irms . The formula for   Irms is given by: where Io is maximum current. Irms is the value that is equivalent to a steady direct current .  We can investigate this by comparing 2 circuits containing lamp each. circuit 1 uses battery as the source, while circuit 2 uses a.c. supply. AC supply is adjusted so that both lamps are equally bright. At this point, DC and AC supplies are transferring energy to the lamps at the same rate (Power).  By equating the Power of both circuits, we can deduce the equation of  Irms as above. Therefore, the d.c. voltage equals the r.m.s. value of the a.c. voltage.  From the the graph below and th...

Deformation of Solids

Deformation of Solids 💗  Solid is characterized by very packed particles and they are not free to move around within the substance. A solid can change its shape when pressure is applied to it. The forces applied to the solids will amend the position of the solid particles and its spacings. This will then changes the external structure or shape and size of the solid, which defines deformation of solids.   Stress  is the measure of the force required to cause solid deformation. A   strain  is the measure of the degree of deformation.  The strain is given as a fractional change in either the length, geometry or volume. It is a dimensionless number.  The greater the stress , the greater the strain . The proportionality constant in this relation is known as the   Young's modulus,Y  .                                    ...
