A voltage divider has a 12 V power source and needs an output voltage of 8 V. What ratio of $\frac{R_2}{R_{total}}$R2​Rtotal​​​ is required?

The voltage divider equation is given by:

V_out = V_in * (R2 / (R1 + R2))

where:

• V_out is the output voltage, which is 8V in this case
• V_in is the input voltage, which is 12V in this case
• R1 and R2 are the resistances in the voltage divider

We are asked to find the ratio R2 / (R1 + R2). Let Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
