All the elements in the circuit shown in the following figure are ideal. Which of the following statements is/are true?

The Zener diode in circuit has a breakdown voltage of 5 V. The current gain $$\beta$$ of the transistor in the active region in 99. Ignore base-emitter voltage drop $$V_{BE}$$. The current through the 20 $$\Omega$$ resistance in milliamperes is ___________ (Round off to 2 decimal places).

Assuming the diodes to be ideal in the figure, for the output to be clipped, the input voltage $${V_i}$$ must be outside the range

A voltage $$1000\sin \omega t$$ Volts is applied across $$YZ.$$ Assuming ideal diodes, the voltage measured across $$WX$$ in Volts is
