A series circuit is a type of electrical circuit in which the components are connected end-to-end in a single loop. The same current flows through each element in a series circuit, but the voltage drops across each component can be different. Understanding series circuits is fundamental for an...

What is stress and strain in mechanical engineering? What is industrial metallurgy? What supplies potential difference to a circuit? What is induction in physics? What is a rheostat? What is a series circuit? What is electromotive force?
Because the circuit is a combination of both series and parallel, we cannot apply the rules for voltage, current, and resistance “across the table” to begin analysis like we could when the circuits were one way or the other. For instance, if the above circuit were simple series, we coul...
In electronics, we can find both series and parallel circuits. A series circuit is a circuit where the components are connected in a consecutive chain. This gives the current only one path to take. A parallel circuit is a circuit where the components are connected parallel to each other. So...
What is a series or parallel connection? As we know from the circuit theory, to achieve a specific power transmission in a system, we can hold the voltage at a fixed level and then increase/decrease the electrical current. It is also possible to fix the current level and then increase/dec...
When you install the batteries, they are in a single row with negative touching positive. This is a series circuit. Each of the “C” batteries is 1.5V. We learned earlier that when batteries run in series, then the output voltage is the sum. In this case, the flashlight runs off 6 ...
