What is direct current?
A form of current electricity where the polarity of the source does not change.
What is the definition of current electricity?
A continuous flow of electrons along a directed path.
Measurement of quantity?
Coulomb, Q, C.
Measurement of potential?
Voltage, E, V.
Measurement of opposition?
Resistance, R, Ohms, Omega.
Measurement of rate of flow?
Current, I, Amps, A.
Measurement of energy converted?
Power, P, Watts, W.
Ohms law?
The current that flows in a circuit is directly proportional to the voltage of a circuit, and indirectly proportional to the opposition in the circuit.
Ohms law mathematically?
I= E/R or E= I x R
Power current and voltage relationship stated?
The power dissipated in a circuit is directly proportional to the voltage of the circuit and the current in the circuit
Power current and voltage relationship formula?
p= i x e
What is a series circuit?
A circuit where there is only only
Path for the electrons to flow from the source, to the load, and back to the source.
What is Kirchhoff’s voltage law? (Series)
The algebraic sum of the applied voltage and the voltage drop around any closed circuit is equal to zero
Kirchhoff’s voltage law simply given?
The voltage drop around any complete circuit is always equal to the applied voltage.
Kirchhoff’s voltage law mathematically?
E= I x R
What is the formula for current, given by Kirchhoff’s current law?
I1 = i2= i3…..
Kirchhoff’s current law stated?
The algebraic sum of the current at any split and junction is equal to zero
Resistance in a series circuit?
The total resistance in a series circuit is equal to the sum of the individual resistances
What is a parallel circuit?
A circuit where each component is directed across the source.
Definition of a parallel circuit?
A circuit where each component is directed across the source
Kirchhoff’s voltage law for parallels?
The algebraic sum of the applied voltage and the voltage drop around any closed circuit is equal to zero.
Kirchhoff’s voltage law for parallels simply put?
The voltage drop around any complete circuit is always equal to the applied voltage
Kirchhoff’s parallel voltage law formula?
et= e1+ e2+ e3
Definition of a compound circuit?
A type of electrical circuit which can be broken down into series portions and parallel portions
