Electric Circuits Flashcards
Series DC
One path, one missing component disrupts the circuit
Parallel circuit
Current multiple paths, one missing component doesn’t disrupt the circuit
DC current
Current does not change direction
AC current
Alternates direction at a high rate
Closed circuit
Free to flow
Open circuit
Break prevents flow
Short circuit
No resistance in a circuit
Electrical current
Flow of electrons, negative to positive
Current
Measured in amps, remains constant through the circuit,
simplified as the rate of current flow
Electrical resistance
The opposite of amps
resistance is the opposition to current flow determined by the physical structure and composition of material
resistors are built to resistance in a circuit
Wattage rating
Heat dissipation capability of a resistor is measured in watts
Ohms law
The circuit current is directly proportional to the applied voltage, current is inversely proportional to circuit resistance I = current amps E = Voltage volts R = resistance ohms P = power watts
