Build the circuit shown in which three LEDs light up.
Three LEDs in parallel circuit. (Enlarge) |
Circuit diagram three LEDs in parallel. |
The LEDs are arranged in a parallel circuit. Each LED requires a resistor in order not to be destroyed.
Consequently, through each LED flows a current of LED of 15 mA, i.e. a total current of 45 mA! The current and hence the energy consumed is three times as big as with a single LED.
Can you connect the LED's smarter?
