Hey guys im ew to this forum and a newbie with electronics, im building a, building model but want to put lights into it. However i have got ultra bright 25mA, 3 foward V white LEDS i hav a 6V power supply (batteries), i want to create a series circuit of 10 LEDs i checked the calculator and have bought 150Ω resistors, a resistor an LEDs on a single circuit (x 2) works but adding others, doesnt give me anything i have attached a image to make it ALOT more clearer. I have read you can make a series circuit and run the LEDs off a 9v supply? If i need to change the ohms or the LEDs (white led running off a 9V (has to be bright)) please could you guide me as i know the little torches can run off that type of power (with about 9 LEDs in them)(coluld you please provide a diagram)
Sorry for my rant and baffle i really am in need of some advice THANKYOU
