Power Dissipation in Resistance

kookie wrote:How does the value of resistor affect the power of the circuits?

The voltage, current or resistance of any series connected circuit can easily be found and resistor of a series circuit can be interchanged without affecting the total resistance, current, or power to each resistor.

What causes a voltage drop?

What is an acceptable voltage drop?

What is the maximum volt drop?

Hndi. Pero panigurado nakakapagod yun para sa kanya. Sa isang relasyong kapag on and off nakakapagod diba?? Ayyy jokeee

Pero sa tingin ko oo, isang factor ding ng mabilis na pagkapundi yung patay sindi, kasi yung sa voltage diba, once na binuksan mo yung ilaw dun nag sstart yung pag push ng voltage sa current. Kaya ayun, sa palagay ko lang naman

HAHAHA! Thanks Draven!

How to read the color coding of a resistor?

I mean how to read the value of a resistor by its' color coding?

You have voltage drop anytime you have resistance and current. To get lower voltage drop you can either lower the resistance or lower the current. You can lower the resistance by going to lower resistance wire, either thicker, or lower resistance per cube, or shorter wires. You can lower the current by drawing less power os by using a higher voltage for the same amount of power.

kc wrote:What is the maximum volt drop?

I wouldn't say maximum, rather permissible voltage drop.

Voltage variations in 33 kV and 11kV feeders should not exceed the following limits at the farthest end under peak load conditions and normal system operation regime.

   Above 33kV (-) 12.5% to (+) 10%.
   Up to 33kV (-) 9.0% to (+) 6.0%.
   Low voltage (-) 6.0% to (+) 6.0%

yung karaniwang alam ko na ginagamit ay Carbon Resistor

Another type is wire wound resistor.

Power created = Power dissipated

Potentiometer

If we are talking here about school, this topic will be a great help.

More like Law of Conservation of Energy.

SInce some other user here ask about voltage drop, I want to ask what causes low voltage in a house? Is it related to "di agad nagbubukas yung ilaw"?

It may take steps:

The first and the second color will be  the 2 values.
third color is for multiplier, for example we have red, red, yellow and gold.
red = 2, so the 2 values is 22, then
the 3rd color, yellow=4, which is multiplier, so
the value 22 will be multiplied in 1000, we will get 22,000 ohms.

For some instances, the resistor doesn't have a 4th bond so the value will be the same.
Hope you understand.
For you to understand it deeply, you can search in the internet. You will get dozens of answer there.

There are two basic types of resistor
Linear resistor
Non linear resistor

Under the linear resistor is a fixed and variable resistor
Fixed resistor consists:
Carbon Composition Resistors
Wire Wound Resistors
Thin Film Resistors
Thick Film Resistors

Variable resistor consist:
1. Potentiometers
2. Rheostats
3. Trimmers
This resistors also have its kinds.

Poor quality or fluctuating power supply can often cause power surges, spikes and voltage fluctuations.

Examples of this can include flickering lights, lights glowing brighter or dimmer, incandescent bulbs blowing prematurely, failure of electronic equipment (especially computers), interference of radio or TV reception.

Yes it is connected. From electric energy to heat energy.

Leon wrote:Power created = Power dissipated

The power that is created through the voltage and current will be used up by the load and its resistance. Bale ang patunay na nagamit yung power or dissipated na ang power is the heat.

aside from resistor what are the other components that dissipates?

RT wrote:aside from resistor what are the other components that dissipates?

Its not actually the resistor that dissipates, it is the power. The resistance of the resistor is one of the reasons why the power is dissipating.
