Resistor X

[MrPandaram]

ELLO ALL.. kinda stuck.... if anyone care to help me out?

Q is.....
two resistors of X ohms and 4 ohms are connacted in series to 20 V d.c supply.
if the p.d across the X ohms is 4V, determine....

1,the p.d across the 4 ohm resistor..
2,the current taken by the supply..
3,the value of resistor X..
4,the power taken by the circuit..


anyone intrested in explaining this poo out to me?

thanks

ello big bad boys...

Since English is not my first language, I had difficulties in understanding some stuff in EAL level 2 stuff.. So i just ask if anyone can explain how to sort this things out, and someone helped.. now I perfectly understand how to do circuits now.. So i worked out rest of the Q i need to do. this is not a homework i just need bit of.. you know bit of spark...... Simple as that..


ps... please go easy on me.. i was out of school at 14 and by the time i am 16 ( when you lot doin 0 levels..) i was doing this..... http://www.youtube.com/watch?v=6LLqwm8ng5Q . so i need lots of catching up to do..


and again thanks for the man with pic..

I’ll apologise to MrPandaram for not being as understanding as I could have been.

That video is one of the most sickening things I have ever seen. Real people getting machine gunned! I am finding it very hard to digest.

I know it goes on. But very shocking to my western sensibilities.

the real ppl who getting shot in the video is.. trained in Selhurst(UK) by SAS.

the real ppl who shooting in the video is.. trained in cambodia by keenie meenie service ( ex SAS)

but hey... you r just a commoner.

 

[MrPandaram]

again.. just wondering....


when you do parallel, reciprocals is easier then product over sum methed ah?

 

[topquark]

Product over sum only works for two in parallel, recip method works for any situation
