Resistors

What happened?

[mapukmapuk]

Dude i got battery 11.5V 2AH and i want resistor that make the battery voltage 4V , how do I can know how much OHMs resistor I need? please help!

@mapukmapuk

Use Ohms law.

Hi there could you explain to me the watts on Ceramic Resistors (used for Audio Speaker Crossovers) i understand the Ohms ie the higher the Ohm the higher the Resistance yeah? but watts? ie 5w 7w 9w 10watt ect. does it make a big difference the watts?never really understood it Thanks.!

@SoundOut260 Didn't deal with electronics since I've been finishing my electronics studies but as far as I remember you have two relations that can explain the power in watt.

Power P Tension U and Intensity I

P = U×I

And the other one is the very first I've been taught

U = R×I were R is resistance.

From these you get

P = R×I²

We used to work with 1/4W resistors. If you consider the last relation you can understand : the more resistance and Intensity the more power (and heat by the way).

@EminoMeneko Many thanks for your quick reply and a Great Answer and i understand you thanks

my amp is 300watts, and it has 2 output terminals. in one terminal, i want to connect a 4 ohm speaker and an 8 ohm speaker in parallel. d 8ohm speaker is 100watts. what kind of resistor to use with it, so it wont be damaged by the excess power. how to connect it? PLEASE REPLY!!!!!!!

@Exutus whats v= ir... thats for calculating voltage..i meant calculating power dissipated as heat in watts,,which i have found now which is p=v^2 / r or p=i^2 x r

but thanks for tryin to help pal ..may if u know more than i do u can answer a few of my other electronics blunders

wtf, still plays wiv lego??, how u work that out?? nd that cumin from sum1 whos only interest in life is how resistant a resistor is, haha.

[kevykev38]

I am learning about resistors can anyone tell me how to find out wattage on a resistor? Calculate?

Any help would be appreciated.

i think that you want

[johnghadlington]

@kevykev38 have you figuered out how to calc wattage as im after that same thing

[foz7410]

u ppl r fukin sad. resistors r gay

[upperlupus1617]

O.o that is so random

@foz7410 thats rich comeing from someone who still plays with lego.

i love these videos by why so short?

[buff2505]

as i said in another vid im learning about all this. Bit mind boggling but im getting there

[davidbball13]

upload more you are great

[huk14]

wow tnx men...can u please upload more on electronic components uses and functions?
