Voltage divider equation6/2/2023 ![]() ![]() ![]() ![]() If we solve this 10 divided by 60 times 120 and in this case we can look at this and see 10 over 60 is going to be one-sixth of 120 is going to be 20 volts, a 20-volt drop… let us just to the next slide I have prepared a circuit for this. In this case, R1 is 10k and the total resistance will be 60. This is the formula RX in this case R1, divided by the total resistance times the applied voltage. Here we have an equation we are solving for V or X and this is what we are solving for and this case we are solving for R1 so we will be solving what is the voltage drop across R1. The voltage divider equation is very useful for determining the relationships in a series circuit. The voltage drops in a circuit are proportional to the resistance values, so what that is saying is that the voltage drops that we will experience in a given circuit are going to be proportional to the values of resistance in that circuit. We are continuing with section 4.2 and in this section, we will be looking at voltage dividers and power equations for series circuits.
