A 1.00-M voltmeter is placed in parallel with a 75.0-k resistor in a circuit. (a) Draw a circuit diagram of the connection. (b) What is the resistance of the combination? (c) If the voltage across the combination is kept the same as it was across the 75.0-k resistor alone, what is the percent increase in current? (d) If the current through the combination is kept the same as it was through the 75.0-k resistor alone, what is the percentage decrease in voltage? (e) Are the changes found in parts (c) and (d) significant? Discuss.
