|R1=4ohms;R2=3ohms Since it is connected in series.
|Kartheek said: (Feb 21, 2011)|
|In series Rt=R1+R2+R3+R4+ ...|

|The effective resistance in series is the sum of resistance. Therefore if a resistance is added in series,the overall resistance will increase. Answer-INCREASES|
|Bharathkumar39 said: (Aug 19, 2011)|
|We know that in series combination R = R1+R1+R3+R4+ .... Rn.
So resistance will increase.
|Gurmangat said: (Sep 18, 2011)|
So resistance will increase.
|Priya.R said: (Sep 20, 2011)|
|In series combination R = R1+R1+R3+R4+ .... Rn.
So resistance will surely increase

|Before three resister which conection.|
|Bhagirath said: (Apr 11, 2012)|
|SUPPOSE,R1=5OHM, R2=6OHM R3=4OHM SO R4=?
IN SERIES, THE RESISTANCE IS 1/R,SO,
R1+R2+R3+R4=MORE THEN R1+R2+R3
SO, RESISTANCE IS INCREASE.

|Since the value of the resistors is not given ,assuming that the fourth resistor R is connected in series with three more resistors the net resistance is R1+R2+R3+R4 = R+R+R+R =4R.
The 4th resistor added increases the resistance by one fourth.( if all the resistance are equal)

|Suppose r1=1ohm, r2=2ohm, r3=3ohm.
Then we know in series R=r1+r2+r3.
Therefore by adding one more resistance it's resistance automatically increases as per in series circuit.
|Meena said: (Dec 15, 2012)|
|Suppose when three resistances are added together then the resistance value will increases, because we know that when they are connected in series then the result will be R=r1+r2+r3.|
|Sravya said: (Jan 27, 2013)|
|When the resistances are connected in series all the resistances are added hence the value of resistance increase.|
|Vasantha said: (Aug 25, 2013)|
|R1 = 6 ohm R2=4 ohm when these two are connected in series i.e. R1+R2=10 ohm so the value is gradually increase so like this the value of the fourth resistor is also increases.|
|Kalai said: (Nov 7, 2013)|
|We know that resistance are connected series R=R1+R2+R3...+Rn.
|Sher Singh Meena said: (May 20, 2014)|
|Because we know that,
R = R1+R2+R3+.......+Rn.
So if another resistor is connected in series then total resistance of the circuit will be increase.
|Parth M Dodia said: (Jul 26, 2014)|
|When resistors are in the series connection, it's resistance are increased because the formula of the series connections is R=R1+R2+R3+....+Rn.|
|Thanu said: (Feb 18, 2015)|
|In a series circuit is R=R1+R2+R3+R4. So resistance will be increase.|
|Santosh said: (Jul 6, 2015)|
|Resistance in series so are R1+R2+R3+R4+.....|
|Pandya Smit said: (Jul 30, 2015)|
|r1+r2+r3 = R.
Resistance are in series so R+r4 . So increase.
|Utkarsh Soni said: (Sep 9, 2015)|
|Obviously the resistance will increase because there's a series connection.
Answer won't be option A, because in series connection there be always addition not multiplication.
|Mukesh Kumar said: (Feb 7, 2017)|
|In the circuit, the total resistance is increased so by ohms law.
|Danish Kamal said: (Mar 2, 2017)|
|Increases, because in Series Circuit.
Rt = R1 + R2 + R3 + R4.
|Sukhwinder Singh said: (Mar 20, 2017)|
|Series resistance increases and current is same R = r1 + r2 + r3 + r4.|
|Romaine Thmpson said: (May 8, 2018)|
|Thank you for explaining the answer.|
|Subhash said: (May 15, 2018)|
|In a series connection, the total resistance is equal to the sum of all resistors as new resistor is added, resistance increases.
For example : if resistors are 1,2,3 ohms then total resistance is 6 ohms.
If 4 ohms is added then total becomes 10 ohms.
|Sadiqul Islam Shamim said: (Jan 24, 2019)|
|R1=4ohms; R2=3ohms Since it is connected in series.
Answer is Increases.
|Supriya said: (Oct 31, 2019)|
|In series Rt = R1+R2+R3+R4+ ..|
