Do these circuits have the same brightness?


not necessarily, brightness of leds depend on current flows through them. if current through leds same brightness same. if 1 resistor , 3 leds in series, 3 leds have same brightness in series configuration. if 1 resistor in series , 3 leds in parallel each other, have same brightness respect each other. brightness of configuration different configuration in series. because current flowing through resistors vary in 2 different configurations

our physics class constructed series , parallel circuits 1 resistor , leds. total resistance, voltage, current, , power between each circuit equal. believe brightness between these 2 circuits same. right or wrong , why?
