Brightness is same and Equal ; Current through a single bulb battery is lesser.
(1) Each bulb receives the same amount of current.
(2) The current through the entire circuit is the sum of the currents through each bulb.
An electrical charge carrier movement known as current often involves electrons or atoms lacking in electrons. The capital letter I is frequently used as a sign for current. Amperes are the commo.n unit and are den0ted by the letter A. I=time charge is a formula that expresses current as the flow of charge per second. Ampere is the name of the current's SI unit. The energy per unit charge is known as voltage, also known as electromotive force. Voltage is the difference in electric potential between two locations, to put it another way. The pace at which an electric charge flows is known as current. Electrons go from a negative potential to a positive potential, and vice versa. The number of electrons that pass through a conductor's cross section in a second is used to calculate current
