A current of 2.50 A flows through a circuit for 8.00 minutes. The current is
supplied by a 12.0 V battery. How much energy is used?
A total resistance of 12.0 is created when two resistors are placed
o Magnets have two sides.
o One side is called North, the other

If we take 2 charged balls with different
charges and we connect a wire between the
balls, the electrons will be free to move from
one ball to the other ball.
This is electric current.
Unit: Ampere, Amp, A
Electric Charge and Fields
o Electric charge like mass is a fundamental
property of nature.
o Unlike mass, charge comes in 2 forms positive
(+) and negative (-).
o Also, where gravity is always attractive; electric
charge can be repulsive
Electric Potential Energy
Unit: Joule, J
o Electrostatic force is conservative.
o If a charge is placed in a constant E
field, it will experience a Force.
If that charge is moved, work will
