## Homework Statement

using complete diode model explain which path will the current follow? given dynamic resistance is 240 ohm.compute current.

**2. The attempt at a solution**

when we make complete diode model, ideal diode will be replaced by a switch and the given dynamic resistance. the silicon diode will be replaced by a 0.7v battery, a switch and the given dynamic resistance.

from figure both the diodes are forward biased.

now as ideal diode has 0v potential drop across itself, it will start conducting the circuit current immediately, preventing the silicon diode to attain 0.7v and thus from turning on. so the current will follow the path through ideal diode.

now we can compute current as, the whole drop of battery is across dynamic resistance of ideal diode so by applying ohms law I=0.041667A.

Now problem is only i want to confirm this solution attempt. is this right or any other modification needed??

thanks
