1
Q
The current in an electrical circuit depends on…
A

They’re rubbed against each other and negatively charged electrons are rubbed off.
3
Q
What happens when a material GAINS an electron?
A
It becomes negatively charged.
4
Q

A
It gains a positive charge.
5
Q
Calculation for current…
A
Amps=charge/time
6
