How to increase the voltage/current of batteries (3 steps)

Sometimes there are projects that we would like to do but there might not be enough power to run it. So we either forfeit the project or abandon it. But with these steps below you can multiply the voltage  or current from your power source.

In this article I will be using 9v battery ( microphone). 

  There are two ways of connecting batteries. either in "series" or "parallel"

                    IN SERIES;                           
Step 1: Gather the materials: You will need four 9v batteries, some wires, tapes/soldering wire and iron. 

Step 2: Start connecting: Solder/tape wires on the two  terminals on each batteries  (I.e + & -).

Step 3: Connect the positive (+) terminal of the first battery to the negative (-)  terminal of the second battery. Also connect the positive terminal of the second battery to the negative terminal of the third battery and so on until the last battery in this case four.

 At the end of the day we will have the wire on the negative terminal  on the first battery and the wire on the positive terminal on the fourth   battery free which are the output to the load.            For more understanding study the image below                     

Note: The higher the voltage the lower current and the higher the current the lower the voltage.

                    IN PARALLEL;                      
Step 1: Gather the materials: You will need four 9v batteries, some wires tapes/soldering wire and iron. 

Step 2: Start connecting: Solder/tape wires on the two  terminals on each batteries  (I.e + & -).

Step 3: In this case all the positive (+) terminals are connected together while all the negative (-) terminals are also connected together.                    For more understanding study the image below.
 
          

Note: The higher the current the lower the voltage while the higher the voltage the lower current.
