Direct Current Circuits-Princeton APPhysics I
coulomb- ✅One ________ per second is an ampere (abbreviated A), or
amp.
✅
higher potential- The longer line represents the positive (________)
terminal, and the shoerter line is the negative (lower potential) terminal.
✅
Electric Current- -Although the electric field would travel through the wire
at nearly the speed of light, the electrons themselves would still have to
make their way through a crowd of atoms and other free electrons, so their
drift speed, vd, would be relatively slow, on the order of a millimeter per
second
Kirchhohoffs Rules- ✅1
Voltage-✅creates a current
Circuit-✅an electric current maintained when the terminals of a voltage
source are connected by a conducting pathway
Electromotive Force (also known as an emf)- ✅The job of the voltage
source is to provide a potential different
✅
First law- The total current that enters a junction must equal the total
current that leaves the junction
✅
Second Law- The sum of the potential differences (positive and negative)
that traverse any closed loop in a circuit must be zero.
