That depends how they are connected. For example, if they are connected in series, just add the individual resistances.

The total resistance for this circuit if all resistors are 200 ohms is?
400 ohms
What is Resistance of 20 ohms and 10 ohms?
Well, the total circuit resistance depends on the type of connection. If the two resistances (or any number of resistances) are connected in series, IE. one resistance end is connected to one end of another resistance, the the circuit total resistance is the sum of the two resistances. say two resistances r1 and r2 are connected in series the total resistance is r1+r2 (in this case its 30 ohms). If the resistances are connected in parallel IE. both the ends of a resistance are connected to both ends of another resistance then the total resistance in this case shall be (r1*r2)/(r1+r2) ,( that is 6.67 ohms in given case).
A cell of emf 3.0 volts and internal resistance of 0.01 ohm is connected through an ammeter of 0.05-ohm internal resistance to a 5.0 rheostat by wire having a total resistance of 0.85-ohm?
total voltage = 4.5V, total resistance = 3.5 ohms, loop current = 4.5V / 3.5 ohms = 1.286Atotal voltage = 9V, total resistance = 4 ohms, loop current = 9V / 4 ohms = 2.25Atotal voltage = 13.5V, total resistance = 4.5 ohms, loop current = 13.5V / 4.5 ohms = 3Aetc.There is no solution to your problem conditions.
What is the total resistance of three resistors in parallel with values of 2 ohms 8 ohms and 14 ohms?
Current, by Ohm's Law, is voltage divided by resistance, so, 18 volts divided by 2 ohms is 9 amperes.
A shaded pole motor coil will have a resistance of approximately?
15 to 40 ohms.
What is the total resistance is V is 10 volts R1 is 1000 ohms and R2 is 1000 Ohms?
If they're connected in series the total resistance is 2000 ohms. If they're connected in parallel the resistance is 500 ohms.

how much resistance must be connected in series with a 250 ohms inductive reactance to produce a total ciruit impedance of 400 ohms?
A series circuit contains an electric generator, three devices operated by electricity, and the necessary connecting wires. The resistances of the three devices are 20 ohms, 8 ohms, and 4 ohms. What is the total resistance in the circuit?
When a resistor is in series. Total resistance =R1+T2+R3. Therefore 20+8+4=32 The total resistance is 32 ohms.

The total resistance of a series circuit containing three 10 ohm resistors is ohms.?
30 ohms
There are three souces of resistance in a parallel circuit Two of them are rated at 20 ohm the other at 10 ohms What is the circuit's total resistance?
Three resistors in parallel: 20 ohms, 20 ohms, 10 ohms.1/ total resistance = (1/10) + (1/20) + (1/20) = (2/20) + (1/20) + (1/20) = 4/20 = 1/5 mho.Total resistance = 5 ohms
