When the electrical devices are connected in parallel there is no division of voltage among the appliances. The potential difference across the devices is equal to supply voltage. Parallel connection of devices also reduces the effective resistance of the circuit.

Advantages of Connecting Electrical Devices in Parallel with Battery

When connecting electrical devices with a battery, there are two ways to connect them: in parallel or in series. Connecting them in parallel offers several advantages over connecting them in series.

1. Equal Voltage Across Devices

When devices are connected in parallel, they all receive the same voltage from the battery. This means that each device can operate at its own individual voltage level without affecting the others. In contrast, when devices are connected in series, the voltage is divided between them, so each device receives a lower voltage than the battery's output. This can result in some devices not functioning properly.

2. Independent Functioning

When devices are connected in parallel, they function independently of each other. If one device fails, the others will continue to operate normally. This is not the case when devices are connected in series. If one device fails, it can cause the entire circuit to fail.

3. Greater Current Capacity

When devices are connected in parallel, the overall current capacity of the circuit is increased. This is because each device has its own path to the battery, which reduces the resistance of the circuit. In contrast, when devices are connected in series, the overall current capacity is limited by the device with the lowest capacity.

4. Easier Troubleshooting

When devices are connected in parallel, it is easier to troubleshoot problems. If one device is not functioning properly, it can be isolated and tested without affecting the other devices. In contrast, when devices are connected in series, troubleshooting can be more difficult because the failure of one device can affect the entire circuit.

Conclusion

In summary, connecting electrical devices in parallel with the battery offers several advantages, including equal voltage across devices, independent functioning, greater current capacity, and easier troubleshooting. These advantages make parallel connection the preferred method for many electrical applications.
