Greetings,
I run a multisim simulated circuit and real life circuit. The circuit I am trying to simulate is a basic oscillator.

The simulator shows that as soon as I turn on and off the circuit, a spike of high voltage occurs and oscillation occurs with a exponential decay. I used a zener diode of 11 V limit. My intention was to create a higher voltage pulse from the lower voltage source. The simulator demonstrated my original intention. However, in real world situation an opposite thing happened. (Note that instead voltmeter I used an oscilloscope for voltage measurements). With a real circuit, there was no oscillation, no spike of higher voltage, instead I got a smoking resistor. The reason I used a small resistor was to simulate battery resistance (for battery charging purpose)and source (9V battery in circuit schematic and real world) as low voltage low current source. My question is
1) why simulation and real circuit test results do not match to each other?
2) why I am not getting oscillation?
3) Is there an alternative to oscillator schematic?
I used 16V 100uF and 16V 220uF capacitors for test. Inductor of 1mH and 6.6ohm resistor. The voltage source was 9V battery.
Thanks for your time.
