statement for Linked Answer Questions 76 and 77
A regulated power supply, shown in figure below, has an unregulated input (UR) of $15$ Volts and generates a regulated output $V_{\text {out }}$. Use the component values shown in the figure.
In the figure above, the ground has been shown by the symbol $\nabla$
If the unregulated voltage increases by $20 \%$, then power dissipation across the transistor $\text{Q1}$
- increases by $20 \%$
- increases by $50 \%$
- remains unchanged
- decreases by $20 \%$
