Circuit

A Parallel + Series Circuit with 2 batteries 2 Bulbs and a switch 

- If I put switch here, The switch Purpose is Just the same if it's Open The Flow of the Energy won't pass through, If it's Close the Energy can go around the wires.

What is Voltage? How does it differ in series vs parallel 

- Voltage is equal to energy per unit charge                

                                               In Series Circuit, - the sum of the 

Voltage Consumed by each individual

 resistance is equal to the source voltage.

- In Parallel Circuit, the voltage across each                                                     ⬇⬇⬇⬇⬇

of the components is the same, and the current                                            ⬇⬇⬇⬇⬇

total is the sum of the currents flowing through                                       ⬇⬇⬇⬇⬇

What is Current? How does it vary in series and parallel?

- An electrical current is said to exist when there is a net flow of electrically charged particle
