In a circuit with two identical lamps in parallel, if the current in one lamp is 0.2
amperes.


a) How much is the current in the battery?

b) If the voltage across the battery is 10 V, how much is the resistance of each
lamp?


c) Calculate the power dissipated by each lamp and the power provided by the
battery.


d) If we remove one lamp and keep one, how much is the current passing
through the lamp that you keep in the circuit? How much is the power
dissipated in this lamp?


e) Does the brightness change if you use only one lamp?
