A circuit contains four 100 ohm resistors connected in series. If you test the circuit with a DMM, you should read a total resistance value of
when the resistors are connected in series , their equivalent resistance is equal to the sum of individual resistance
R(equi) = R1 + R2 + R3 + R4
R(equi) = 100 + 100 + 100 + 100
= 400 ohm
so the test circuit will read 400 ohm

A 6.0 V battery is connected to two 7.70 kilo-Ohm resistors in series. An ammeter of internal resistance 0.570 Ohm measures the current and at the same time a voltmeter with internal resistance 15.2 kilo-Ohm measures the voltage across one of the 7.70 kilo-Ohm resistors in the circuit. What does the ammeter read? What does the voltmeter read?

(5.38) The design of an electronic circuit calls for a 100-ohm resistor and a 250-ohm resistor connected in series so that their resistances add. The components used are not perfectly uniform so that the actual resistances vary independently according to normal distributions. The resistance of 100-ohm resistors has mean 100 ohms and standard deviation 2.5 ohms, while that of 250-ohm resistors has mean 250 ohms and standard deviation of 2.8 ohms. (a) What is the distribution of the total resistance...

Consider a circuit with two 10 ohm resistors in series and connected to a 6 V battery. A certain current flows through it. What would happen to that current if you added a third 10 ohm resistor in series with the other two? Would the current increase, decrease, stay the same, or become zero after you added the third resistor? Give a short justification of your answer.
