i was being ask to describe the energy changes involved in the use of mobile phones and a television
i m noot even sure i have fully understand the question,
energy change? say in mobile phone, all i can think of is signal wave turns to electric pulse which then changes into digital data... but it seem rather to staright forward so is there any other changes/?/
any energy invloves chemical or kinetic or potential ?
thanks
