Task $1$: Powering the load using a $15$ V battery pack $(25$ points$)$

Assume that you are given an ideal $15$ V battery pack $($ideal independent voltage source$)$ to power the following loads, Load information:

Heating element information:

Rated voltage: $10$ V

Rated power: $10$ W

Bulb information:

Rated voltage: $10$ V

Rated power: $20$ W

Design the necessary circuit to supply these loads from the $15$ V source without violating the voltage and power requirements of both the loads.

please include the circuit diagram
