ELECRIC CURCUITS Flashcards
1
Q
How does friction work?
A
Some insulators become charged when you rub them with another insulator such as a dry cloth. When you rub the insulator, electrons are transferred from one of the materials to the other.
2
Q
Key points-
A
- electrons are transferred when objects become charged
- insulating materials that become positively charged when rubbed lose electrons
3
Q
What happens if the resistance is low?
A
This means that the current is highly through it
4
Q
What’s the main volts?
A
240v
5
Q
The equation for power?
A
Power equals energy divided by time
