U=RI Ohm's law
then R=U/I
=120/0.08
=2250Ω
hope this helps you
The electrostatic force between two charges is given by Coulomb's law:

where
ke is the Coulomb's constant
q1 is the first charge
q2 is the second charge
r is the separation between the two charges
By substituting the data of the problem into the equation, we can find the magnitude of the force between the two charges:
Answer:
R=V/I=6/2=3ohm
time =5minutes =5*60=300seconds
I=2A
Heat =I^2Rt=(2)^2*3*300=4*900=3600J
A positive charge cause dosent your hair static up when that happens or no?
The answer would be (A) Protons
