Challenge Problems
Push your limits with challenges.
Question 1
You recorded a voltage of 8.5 V across a resistor using a voltmeter that has an internal resistance of 20 kΩ in a circuit with a total series resistance of 100 kΩ. Calculate the actual voltage across the resistor and discuss the implications.
💡 Hint: Consider how much current flows and how parallel resistance affects readings.
Question 2
A voltmeter connected across a resistor with a high resistance reads 11 V. If the resistor is actually part of a circuit supplying 24 V total, what could be happening? What would you expect to happen if you change to a higher resistance voltmeter?
💡 Hint: Think about how voltmeter specifications might lead to differences in readings.
