The actual resistance on a 10 ohm resistor is ten ohms.
The actual resistance on a 5 ohm resistor is five ohms.
If these two resistors are connected in series, the actual resistance is fifteen ohms.
If these two resistors are connected in parallel, the actual resistance is three and one third ohms.

Manufactured resistors have a tolerance between their nominal value and their actual value. This tolerance is expressed in percent and is indicated on the body of composite resistors by an additional colored band after the multiplier band. A gold band indicates 5% tolerance, a silver band indicates 10%, and the absence of the band indicates 20% tolerance.

is it a parallel or series circuit?
if it is parallel then:
( 1/10 + 1/5) ^-1 = 3.33 ohm
if it is series then:
10 + 5 = 15 ohm

Series or parallel?
If they are connected in series, the result is 10 ⦠+ 5 ⦠= 15 â¦
If they are connected in parallel: 1/(1/10 + 1/5) = 3.33 â¦

generally resistors can be off as much as 20%, this slight varies from manufacturer to manufacturer. many times people will use a resistor and a pot to adjust and ensure the accuracy. I'm not sure, but i think you need to be more specific.

Resistance depends on potential difference and current.
Without them, the resistors are in stasis.
