formula for " I "
Q/t (remeber cutie)
formula for voltage
E/Q
Ohms Law is
V = IR
What do conductors do?
Allow electric current to flow
what do isalators do
Prevent electric currect flow
what is the law of electric charge?
Like charges repel, opposite charges attracts (like a battery)
what is static by contacts
can tranfer a charge by touch
