Series and Parallel Circuits

Circuit:

• In Electronics, a circuit is a way between two or more focuses along which an electrical current can be conveyed. It is a complete course of conductors through which current can travel.
• Circuits comprising of only one battery and one load resistance are very easy to investigate, however they are not regularly found in practical applications. Typically, we find circuits where more than two parts are associated together.

There are two basic types of Electronic Circuit:

1. Series Circuit
2. Parallel Circuit
3. Series Parallel Circuit: This is a combination of above both.

1. Series Circuit

• In series circuit, resistors are arranged in a chain, so the current has only single path to take. 
• The current is the same through every resistor. The total resistance of the circuit is found by just including the resistance values of the individual resistors.
• A series circuit has more than one resistor, charges must move in "series" first going to one resistor then the following.
• If one of the items in the circuit is broken then no charge will travel through the circuit, the reason is there is only one path. 
• Series Circuits are the least complex to work with.

2. Parallel Circuit:

• A parallel circuit has more than one resistor, charges can travel through any of a few ways.
• The current in a parallel circuit separates, with some flowing along every parallel branch and re-joining when the branches meet once more. The voltage over every resistor in parallel is the same. 
• In parallel circuit the resistors are arranged with their heads associated together, and their tails associated together.

Problem with Series Circuit:

• If u add more devices in the circuit, the current will go down since all the current go through each devices(resistor).
• If you remove a light bulb or one breaks down, the entire series is turned off.

Parallel Circuit - Pros & Con:

• In parallel circuit, adding ,more devices does not decrease the current.
• By breaking of one resistor, the rest won't affect.
• Current doesn’t stay the same for entire circuit, so energy is spent quicker.

Series Circuit - Voltage:

• Voltage is the electric equivalent of water pressure.
• The higher the voltage, the quicker electrons will course through the conductor.
• Every segment has resistance that causes a drop in voltage (decrease in voltage).
• Total Voltage = The whole of voltages over every series resistors.
• Voltage is decreased by every resistance.
 

Parallel Circuit - Voltage:

• A charge just goes through a single resistor. 
• Voltage drop over the resistor that it chooses to go through must equivalent the voltage of the battery.
• Total voltage = the voltage over every  individual resistor

Series Circuit - Resistance:

• Resistors – resists the stream of electrical current.
• Expanded resistance will lessen the rate at which charge flows.
• Total Resistance = Sum of all resistors in the series.
• Total resistance will go up because all of the current must go through every resistor.

Parallel Circuit - Resistance:

• Resistors included one next to the other.
• Since the circuit offers two equal pathways for charge flow, just 1/2 the charge will choose to go through a given branch.

Series Circuit - Current:

• Current is the amount of charge, like flow of water.
• A current can't just vanish (show up), since only one path if some electrons flow through R1, then they need to keep coursing through R2 and R3.
• Use Ohm's law to discover current using resistance and voltage

Parallel Circuit - Current:

• ALL ways are utilized, in any case, the charge divides up into all branches. 
• One branch can have more current than another  branch, depends on resistance in branch.
• Total current = sum of current in every path.

Conclusion:

- In a series circuit, all components are associated end-to-end, framing a single path for electrons to flow.

- In a parallel circuit, all parts are associated over each other, shaping precisely two sets of electrically common points.

- A “branch” in a parallel circuit is a path for electric current shaped by one of the load components.
