Problem 54

A 0.0200- ammeter is placed in series with a 10.00- resistor in a circuit. (a) Draw a circuit diagram of the connection. (b) Calculate the resistance of the combination. (c) If the voltage is kept the same across the combination as it was through the 10.00- resistor alone, what is the percent decrease in current? (d) If the current is kept the same through the combination as it was through the 10.00- resistor alone, what is the percent increase in voltage? (e) Are the changes found in parts (c) and (d) significant? Discuss
