I have a basic electronics question I'd like to put by some of the resident guru's here.
Based on my desire to learm more about electronics design and tangent's review I recently purchased "The Art of Electronics" and I'm very impressed so far. I'm about halfway through chapter two, and I've hit a bit of a stumbling block. How do you calculate the dissipation of a resistor/transister/zener diode in a circuit?
I understand P=I^2*R and P=V^2/R, and where they come from. I have no problem calculating the dissipation of a lone component, but I don't know who to apply it to a circuit, like the voltage regulator in exercices 2.3 and 2.4 (pg 68 and 69 respectivly).
I feel I must be missing something simple.
Thanks for any help
