Compare the properties of copper and graphite to decide which material would be better for making a phone charger wire?

Electrical conductivity is a measure of how well a material transports an electric charge and an essential property in electrical wiring systems. Annealed copper has a superior conductivity compared to all other electrical conductors and became the international standard. Aluminium has 61% of the conductivity of copper, if the cross-sectional areas of both conductors are the same. Silver, however, is the only metal with a higher electrical conductivity than copper - though it is much more expensive

Umra Hayat

Queen Mary University of London alumnus and 5+ years Private tuition experience

I studied English BA at Queen Mary for three years and during my degree I taught English GCSE part time. I am an enthusiastic teacher who inspires student's to reach and exeed their potential. My students in the past have been able to make massive progress because I tailor the lesson to suit their individual needs. I am able to balance work with personal development as I believe both are linked together. Through realising their potential a student can become more self confident in themselves as well as the subject.

I have 8 years professional experience across 5 sectors, including many years Teaching and 1 year in Journalism. During my professional career I have taught for two companies, across four centres providing me with an abundance of experience working with children and a deep understanding of learning techniques. Additionally I also have an understanding of the importance of relaying information to parents regarding progress to make sure all parties are up to date and in sync to a common goal. Other teaching experience includes having had the opportunity to teach English in three countries across the world as a TEFL English teacher.

To do this my method of teaching includes gently pushing academic boundaries to expand on their current knowledge whilst keeping the lessons informative and interesting. Outside of my professional life I am a family oriented person who regularly spends time volunteering for different charities.
