In series, you just add the resistor values together to find the total resistance.
In parallel you can use the following equation you can find the total resistance by multiplying the lowest and highest resistor value, the dividing that by the sum of all the resistor values you have in parallel. you could also take the inverse of all the inverses of you resistor values added together.

When a resistor is connected in parallel what happens to the size of current form the battery?
When a resistor is added the current goes down, that is expressed in the equation current= voltage/ resistance
Voltmeter is connected in parallel with resistor?
A voltmeter can be connected in parallel with a resistor to show the voltage across the resistor.
When the resistor removed from a parallel connection of the circuit whether the resistance increase or decrease?
if we remove a resistor from the parallel connection the effective resistance value will be increased.
What resistance must be connected in parallel to 6.0-ohm resistor to reduce the combined resistance to 15-ohm?
No such resistor exists. Any resistor placed in parallel with a 6.0 ohm resistor is going to reduce the combined resistance below 6.0 ohms.
If a 15-ohm resistor is connected in parallel with a 30 ohm-resistor the equivalent resistance is?
Rt = 10

Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
What is equivalent wattage when different wattage resistors are connected in parallel?
In order to determine this, it will be necessary to find which resistor 'maxes out' at the lowest voltage. This can be found using the equation Vi=sqrt (Pi*Ri) for each resistor, where Pi is the power rating of resistor i and Ri is the value of resistor i. Once this is found, the power dissipation of each other resistor can be found using the equation Pi=(Vl^2)/Ri, where Vl is the voltage that maxes out the resistor which maxes out at the lowest voltage, and Ri is the resistance of each resistor. The equivalent power rating would then be the sum of the power dissipated across each resistor.
How do resistors act in parallel?
Parallel resistors act like a resistor smaller than the smallest parallel resistor. Calculate as 1/(1/R1+1/R2+1/R3...)

What is the total resistance of a 5-ohm resistor and a 10-ohm resistor in a parallel series?

Why are resistances parallel to short circuits neglected in a circuit?
You can consider a short circuit to be a resistor with R=0 Ohms. It is then clear by the equation for calculation of parallel resistance that the combined resistance of a resistor in parallel to a short circuit is 0. Consider the following example with R1= 1k Ohms and R2= 0 Ohms: Rtotal = R1*R2 / (R1+R2) = R1*0 / R1 = 0 Ohms.
What is the difference between Serial and Parallel Adder?
Some key differences between a Serial and Parallel Adder are that a Serial Adder is slower, a Parallel adder is a combinational circuit and the time required for addition depends on the number of bits in a Serial, but not a Parallel. A Serial Adder is a sequential circuit while a Parallel is a combinational circuit.
