How do i make a circuit using less than 20 components to see the existence and non existence of a flyback diode in which the circuit drives an inductor load . I have a budget constraint of Rs. 50 so please avoid suggesting costly components. I have to see the results on a CRO. A simplified answer would be appreciated . I can also modify the attached circuit which i have already made. But in this circuit i could not see the output on the CRO as the time in which the output occured was very small. Now if i want to see the output what will i have to do to ?Thanks in advance.
