Switch
Flow in own direction, from negative to positive; and supplied through dry cell or storage battery
Direct current
Constant reverse in direction of flow; produced by a generator

Used in measurements of temperatures
Thermocouple
Sources of electrical pressure:
Uses electromagnetic induction principles to produce electricity
Generators
Principles of Resistance:
The higher the voltage, the ___ the current
Larger
Principles of Resistance:
The higher the resistance, the ___ the current
Lower
States that the current in an electric circuit is directly proportional to the impressed emf (potential) applied to the circuit and inversely proportional to the equivalent resistance of the said circuit
Ohm’s law
Rate of using or consuming the electrical energy
Electric power
The rate in which energy is used
Power
Individual resistance in the circuit are connected end to end and there is only current that flies all through out the closed path.
Series circuit
Single path exist for current flow; elements are arranged in series one after the other, no branches; current is the same but the voltage differ
Series connection
The individual resistance are connected across each other and the value of the potential (emf) across is the same.
Parallel circuit
Multiple connection, standard arrangements for house wiring connections,; voltage is the same but current differs.
Parallel connection
A combination circuit which when simplified will result to a series circuit.
Series-Parallel Circuit
A combination circuit which when simplified will result to a parallel circuit
Parallel-Series Circuit
Kirchoff’s Law:
The algebraic sum of the current at any junction or node of an electric circuit is zero
Current Law (KCL)
The algebraic sum of the voltage in any closed loop of an electric circuit is zero
Voltage Law (KVL)
Simple state device consisting of magnetic core where in the primary and secondary windings are made.
Transformer
