Electromotive force is work done to move one coulomb in a complete circuit

E= I(R+r)

Resistivity is a measurement for opposing flow of electric current

Nichrome is the best choice for heating element BC high resistivity -> high resistance

Ohm's Law= resistance is directly proportional to resistance and current if there is no change in temperature.

R=V/I

P= VI

I= Q/t

Time should be measured in seconds

Series circuit

Total R= R+R+R

V,= V+V+V

I= I= I = I
