Calculating Current and Power in Resistors: A Comprehensive Guide

[the_d]

can any1 clue me into how u calculate the current through a resistor and the power absorbed by a resistor please!?

 

[the_d]

Do I use Ohms Law V = i * R?

 

[wayneo]

use I = V/R then for power, P = VI

 

[the_d]

ok thanks wayneo i have another question, how do i find the equivalent resistance seen by a source?

 

[wayneo]

i don't rely understand the question soz

thats cool i think i got it thanks for ur help on the 1st partz
