In a circuit with total voltage of 50V across three resistors in series: R1 = 15Ω, R2 = 25Ω, and R3 = 60Ω. Find the voltage across R2 and explain each step.
💡 Hint: Be sure to double-check calculations of total resistance.
If you need to design a sensor circuit requiring 9V across a specific resistor of 50Ω, and you have 40V total supply. Identify two other resistors that will allow you to achieve this, and show your calculations.
💡 Hint: Think creatively; you may have multiple resistor configurations!
