r1+r2+r3 = R.

Resistance are in series so R+r4 . So increase.

Resistance in series so are R1+R2+R3+R4+.....

In a series circuit is R=R1+R2+R3+R4. So resistance will be increase.

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.

R1=4ohms;R2=3ohms Since it is connected in series.
R=4+3=7ohms. Ans.Increases.

We know that resistance are connected series R=R1+R2+R3...+Rn.

Resistance increase.

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.

When the resistances are connected in series all the resistances are added hence the value of resistance increase.

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.

Suppose r1=1ohm, r2=2ohm, r3=3ohm.
Then we know in series R=r1+r2+r3.
i.e 1+2+3=6ohm.
Therefore by adding one more resistance it's resistance automatically increases as per in series circuit.
