Question

In a series circuit, all components are connected end-to-end, forming a single path for current flow. In a parallel circuit, all components are connected across each other, forming exactly two sets of electrically common points.
What does he mean by saying In a parallel circuit, all components are connected across each other?Explain this to me with a diagram

Answer 1

Explanation:

First, an example of a series circuit:

series circuit

Here, we have three resistors (labeled R1, R2, and R3) connected in a long chain from one terminal of the battery to the other. (It should be noted that the subscript labeling—those little numbers to the lower-right of the letter “R”—are unrelated to the resistor values in ohms. They serve only to identify one resistor from another.)

The defining characteristic of a series circuit is that there is only one path for current to flow. In this circuit, the current flows in a clockwise direction, from point 1 to point 2 to point 3 to point 4 and back around to 1.

Parallel Circuit Configuration

Now, let’s look at the other type of circuit, a parallel configuration:

parallel circuit

Again, we have three resistors, but this time they form more than one continuous path for current to flow. There’s one path from 1 to 2 to 7 to 8 and back to 1 again. There’s another from 1 to 2 to 3 to 6 to 7 to 8 and back to 1 again. And then there’s a third path from 1 to 2 to 3 to 4 to 5 to 6 to 7 to 8 and back to 1 again. Each individual path (through R1, R2, and R3) is called a branch.

The defining characteristic of a parallel circuit is that all components are connected between the same set of electrically common points. Looking at the schematic diagram, we see that points 1, 2, 3, and 4 are all electrically common. So are points 8, 7, 6, and 5. Note that all resistors, as well as the battery, are connected between these two sets of points.

And, of course, the complexity doesn’t stop at simple series and parallel either! We can have circuits that are a combination of series and parallel, too.

Answer 2

Answer:

In a parallel circuit, all components are connected across each other, forming exactly two sets of electrically common points.

Explanation:

First we go step by step:

Step (1) : Learn about Series combination of resistors.

Series Combination: When two or more resistors are connected tail - tail in a circuit then we can say the following connection as Series connection. And in series connection the current flows through every resistor is same but the voltage drop across every resistor is different.

Step(2) : Learn about parallel combination of resistors.

Parallel Combination:  

The primary concept of a “parallel” connection, on the opposite hand, is that each one components are linked throughout every other’s leads. In a only parallel circuit, there are never more than two  sets of electrically common points, regardless of what number of components are linked. There are many paths for current flow, however only one voltage throughout all components.
