A 224- resistor and a 589- resistor are connected in series across a 90.0-V line. (a) What
Question:
(a) What is the voltage across each resistor?
(b) A voltmeter connected across the 224- Ω resistor reads 23.8 V. find the voltmeter resistance.
(c) Find the reading of the same voltmeter if it is connected across the 589-Ω resistor.
(d) The readings on this voltmeter are lower than the “true” voltages (that is, without the voltmeter present). Would it be possible to design a voltmeter that gave readings higher than the “true” voltages? Explain.
