Discover the resultant resistance of multiple resistors linked in either series or parallel arrangements.
Utilize this online calculator to compute the overall resistance within a circuit. In a series circuit, the total resistance is acquired by summing the values of individual resistors. For a parallel circuit, the total resistance is derived by adding the reciprocals of resistor values and then taking the reciprocal of that sum.

Where:
- R1 = Total Resistance by Vt and It
- R2 = Total Resistance by Vt and Pt
- R3 = Total Resistance by Pt and It
- Vt = Total Voltage
- It = Total Current
- Pt = Total Power
