I have looked and looked in the all about circuits...This newbie is still stuck on 2 problems.
What formulas do I use if they are looking for a CURRENT drain if P=7.5 and E=120?
R is not known and I is not known.
I also am looking for the VOLTAGE required to cause a dissipation of 10W in a resistor when I through the resistor is 150Ma.
If some one can just show me how to solve for these I will be greatful !
