- electric shock and burns from contact with live parts.
- injury from exposure to arcing, fire from faulty electrical equipment or installations.
Why is mains electricity more dangerous than batteries?
Answer:The higher the voltage of a battery, the more potential energy per coulomb of charge it can supply. … Mains electricity, 240 volt has much more potential energy per coulomb than a 1.5 volt cell. This is what makes mains electricity so dangerous, with enough energy to seriously injure or kill.
Why is electricity dangerous?

What is the difference between batteries and mains electricity?
Mains electricity is when items are plugged into electrical wall sockets. These normally need a higher amount of energy as batteries would quickly run out if they were used. Electricity is often used with larger appliances that normally stay in one place. Battery operated devices tend to be smaller and more portable.
What voltage is the mains electricity?
The voltages are generally in the range 100–240 V (always expressed as root-mean-square voltage). The two commonly used frequencies are 50 Hz and 60 Hz. Single-phase or three-phase power is most commonly used today, although two-phase systems were used early in the 20th century.
Do humans produce electricity?
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.
