In a simple basic circuit, which typically consists of resistors arranged in series or parallel, the total resistance can be greater than, less than, or the same as the resistance of the individual resistors, depending on how the resistors are connected:
1. **Series Connection**: When resistors are connected in series, the total resistance (R_total) is the sum of the individual resistances (R1, R2, R3, ...):
\[
R_{\text{total}} = R_1 + R_2 + R_3 + \ldots
\]
In this case, the total resistance is greater than any individual resistor.
2. **Parallel Connection**: When resistors are connected in parallel, the total resistance is calculated using the formula:
\[
\frac{1}{R_{\text{total}}} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3} + \ldots
\]
In this scenario, the total resistance is less than the smallest individual resistor in the network.
3. **Single Resistor Circuit**: If there is only one resistor in the circuit, then the total resistance is equal to the resistance of that individual resistor.
In summary, the total resistance in a circuit can be greater than, less than, or equal to the resistance of the individual resistors, depending on how they are arranged.
