1. The problem statement, all variables and given/known data Determine Vout, the current flowing through R and power power dissipated the Zener diode. 2. Relevant equations Circuit analyzing techniques. 3. The attempt at a solution I've done this problem by assuming each diode is off while ignoring the other. E.g. Applying KVL: -24+VD=0 --> VD=24 (Silicon diode is on and will be replaced with 0.7V voltage source). Applying KVL again: -24-VDZ --> VDZ=-24 (Zener diode is reverse biased and will be replaced with VZT, which 12V voltage source). Is this approach correct?
