8 How to convert 12V to 6V step down circuit
VB = 12V, VL = 6V So VR1 = 12V – 6V = VR1 = 6V. From the theory: R1 = VR1 / IR1 So, R1 = 6V / 0.5A = 12 ohms. Next, we need to find the power of resistor-R1. PR1 = VR1 x IR1 = 6 x 0.5 = 3W. So, You should Resistor size is 3W. Also, you can use a 6V relay to 12V by helping of a resistor. Too hot and big. We will see that if used a too high
