Experiment 7 - Ohm's Law and Circuit Topology Flashcards
States that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points, and inversely proportional to the resistance (R) between them
Ohm’s Law
Serves as a foundational principle for analyzing and understanding electrical circuits and is essential in various fields such as electronics, telecommunications, and power systems.
Ohm’s Law
Formula of Ohm’s Law
I = V/R
The arrangement or structure of electrical components within a circuit or system.
It describes how components such as resistors, capacitors, inductors, and various other devices are connected to each other to form a functional electrical network.
It outlines the configuration of connections and pathways through which electric current can flow within a circuit
Electrical Topology
Two (2) Basic Topologies of Electrical Circuits
Series & Parallel Circuits
Ttype of circuit configuration in which the components are connected end-to end, forming a single pathway for the flow of electric current
Series Circuit
In a series circuit:

Total voltage drops in this is equivalent to its ________
same, supply voltage
Series Circuit Relationships (current, voltage, resistance)
I = I_R1 = I_R2 … = I_Rn
V = V_R1 + V_R2 … + V_Rn
R_EQ = R1 + R2 … + Rn
A configuration where the components are connected across common points, creating multiple pathways for the flow of electric current.
It has each component is connected across the same voltage source, forming parallel branches
Parallel Circuit
Parallel Circuit Relationships (current, voltage, resistance)
I = I_R1 + I_R2 … + I_Rn
V = V_R1 = V_R2 … = V_Rn
1/R_EQ = 1/R1 + 1/R2 … + 1/Rn
