Lesson 2: Equivalent Resistance Flashcards
It is an interconnection of electrical elements linked together in a closed path so that an electric current may flow continuously.
Electric circuit
What are the parts of a circuit?
Branch, Node, and Loop
This represents a single or multiple elements such as a source or a load.
Branch
It is the point of connection between two or more branches.
Node
What node is located in between two branches?
Minor node
What do you call the node where three or more branches are connected to it?
Major node
It is an interconnection of branches forming a closed path in a circuit.
Loop
Which circuit comprises a path along which the whole current flows through each component and is the same throughout?
Series circuit
Which circuit comprises branches so that the current divides and only part of it flows through any branch and the voltage is the same throughout?
Parallel circuit
How do you get the equivalent resistance for a series circuit?
Add all resistance
How do you get the total voltage in a series circuit?
Add all voltage
In the parallel circuit, what happens to the voltage?
The total voltage is the same/equal with the individual voltages
How do you get a total current in a parallel circuit?
Add all individual currents
How do you get the equivalent resistance in a parallel circuit?
If you are required to get 3 or more resistance, add all of the reciprocal of each resistance (eg. 1/R1).
If you are rewuired to get the Req of only 2 resistances, multiply the 2 resistances then divide by the sum of the 2 resistances ; Req = (R1)(R2) / R1+R2
What are the two types of the three nterminal network?
Delta (Δ) and Wye (Y)
