What are the differences between series and parallel connection?
Difference between series and parallel circuit A circuit is said to be a series circuit when the flow of current is the same throughout all the components in the circuit. In a series circuit, all the components are arranged in a single line. In a parallel circuit, all the components are arranged parallel to each other.
What are two important differences between a series and a parallel circuit?
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 happens when two cells are connected in parallel?
When cells are in parallel the total voltage is the same as the voltage of each individual battery. The current also remains the same. However, when connected in this way the cells last longer.
What situation is it beneficial to combine cells in series?
1 Answer. (i) It is advantageous to connect cells in series if the external resistance is large enough compared to the total internal resistance of cells. (ii) It is advantageous to connect cells in parallel if the internal resistance of each cell is high enough compared to the external resistance.
What is the principle of electrochemical cell?
Electrochemical cells are devices based on the principle that when a chemical oxidation-reduction reaction takes place, electrons are being transferred from one chemical species to another.
What is electrochemical series?
Electrochemical series also sometimes referred to as activity series is a list that describes the arrangement of elements in order of their increasing electrode potential values. The series has been established by measuring the potential of various electrodes versus standard hydrogen electrode (SHE).
What is electrochemical series example?
The electrochemical series, also known as the activity series, is a list of metals listed in order of decreasing reactivity or in order of decreasing ease of oxidation. Reduction always takes place at the cathode, and oxidation at the anode. Electrochemical series of metals. Look at the series.
