Question 1:
Design and build a typical household electrical system that shows and demonstrates how electricity is used to charge a phone battery from 0-100%. E.g. wires going into a house/wire going from mains to socket/phone charger to the phone.
Show calculations on what it would typically cost to charge a mobile phone at home.
Question 2:
Similar to Question 1, Design and build a typical household electrical system that uses solar panels.
Show calculations on what it would typically cost to charge a mobile phone and compare them to question 1.
Comment on your findings and the difference between Question 1 and Question 2.
*You may use any software or hardware to build the household electrical system for both questions. Include diagrams/coding if doing so*
