how does a material become charged?
becomes negatively charged by gaining electrons
becomes positively charged by losing electrons
what will two objects carrying the same type of charge do if they are brought close to eachother?
repel eachother
what is electric current?
rate of flow of charge
what is the same at all points when charge flows in a closed loop?
current
what must there be in a closed circuit so that electrical charge can flow?
source of potential difference
what happens to the current if the resistance increases but the potential difference stays the same?
current decreases
what is an ohmic conductor?
conducter where current is directly proportional to the voltage so resistance is constant
