Who operates electrical equipment?
: one who installs, maintains, operates, or repairs electrical equipment.
Can humans have electric powers?
Electricity is everywhere, even in the human body. … The elements in our bodies, like sodium, potassium, calcium, and magnesium, have a specific electrical charge. Almost all of our cells can use these charged elements, called ions, to generate electricity.
Who was the person responsible for naming the electric charges?
1747 – Vitreous Electricity, Conservation of Charge
(William Watson (1715-87) in England independently reached the same conclusion.) To identify these two forces, he gave the names, positive and negative charges and to symbolize them, he used the + and – signs the + being for positive and the – for negative.
What do electricians install?
