A power supply has a fixed output voltage of 12.0V, but you need VT = 3.5 V
Question:
A power supply has a fixed output voltage of 12.0V, but you need VT = 3.5 V output for an experiment.
(a) Using the voltage divider shown in Fig. 19-78, what should R2 be if R1 is 14.5 Ω?
(b) What will the terminal voltage be VT if you connect a load to the 3.5-V output, assuming the load has a resistance of 7.0Ω?

I have been teaching college students in various subjects for 9 years now. Besides, I have been tutoring online with several tutoring companies from 2010 to date. The 9 years of experience as a tutor has enabled me to develop multiple tutoring skills and see thousands of students excel in their education and in life after school which gives me much pleasure. I have assisted students in essay writing and in doing academic research and this has helped me be well versed with the various writing styles such as APA, MLA, Chicago/ Turabian, Harvard. I am always ready to handle work at any hour and in any way as students specify. In my tutoring journey, excellence has always been my guiding standard.
