In a large current circuit, using large resistors in parallel is preferred over using low resistors in series because it allows for better distribution of the current and reduces the overall resistance in the circuit.
When resistors are connected in parallel, the total resistance of the circuit decreases because the current has multiple paths to flow through. This means that more current can flow through the circuit, resulting in a higher overall current.
On the other hand, when resistors are connected in series, the total resistance of the circuit increases because the current has to flow through each resistor in succession. This limits the amount of current that can flow through the circuit, resulting in a lower overall current.
Therefore, using large resistors in parallel in a large current circuit allows for more current to flow through the circuit, which can be beneficial in applications where high current is required. Additionally, using large resistors in parallel can help to distribute the current more evenly throughout the circuit, reducing the risk of overheating and potential damage to the components.

In a large current circuit, resistors in parallel are preferred to resistors in series due to the following reasons:
1. Current Distribution:
- In a parallel circuit, the same voltage is applied across each resistor, so the current divides between them. This allows for a more uniform distribution of current.
- In a series circuit, the current flows through each resistor in sequence, limiting the overall current capacity.
2. Power Dissipation:
- Resistors dissipate power as heat, which can lead to overheating and damage.
- In a parallel circuit, the power dissipation is divided among the resistors, reducing the amount of heat generated by each one.
- In a series circuit, all the current flows through each resistor, resulting in higher power dissipation.
3. Reliability and Fault Tolerance:
- If one resistor fails in a parallel circuit, the current can still flow through the other resistors. This provides redundancy and fault tolerance.
- In a series circuit, if one resistor fails, the entire circuit is broken.
4. Voltage Regulation:
- In a parallel circuit, the voltage remains constant across all resistors.
- In a series circuit, the voltage drops across each resistor, reducing the voltage available at the end of the circuit.
5. Cost and Availability:
- Large resistors in parallel are typically less expensive and more readily available than low resistors in series.
Therefore, for circuits requiring high current, it is preferable to use large resistors in parallel to ensure uniform current distribution, reduce power dissipation, enhance reliability, maintain voltage regulation, and optimize cost and availability.
