Difference between parallel and series circuit |
| Answer» Series circuit:\tAll components in a series circuit can be controlled by a single switch. This results in the closing down of all components when the switch is turned off.\tIn a series circuit, current through all the components remain the same.\tA series circuit stops working if any one of its component stops functioning. This happens due to an incomplete path of the current.Parallel circuit:\tIn a parallel circuit, all components require an individual switch. Hence, closing of any switch will not effect the functioning of other components.\tIn a parallel circuit, potential difference across the entire component remains the same.\tA parallel circuit continues to work even when any one of its component stops functioning. This happens because the current continues to flow through the other parts of the circuit. | |

,what are the disadvantages of series combination |
| Answer» In series arrangements -----------------------------1)If one appliance gets fused or switched off then other appliances will also stop working due to breakage of whole circuit. 2)All appliances have one switch hence appliances can\'t be operated independently by different switches. 3)Voltage(p.d) is being shared among different appliances hence all appliances do not get the required voltage to work properly. 4) Magnitude of resistance is maximum due to which small amount of current from the power supply line. Hence high power rating appliances like A.C ,geysers needing high current can\'t work properly. 5)Electrical appliances need current of different values to operate properly. | |

Why do plants take oxygen at night and release co2 |
|
Answer» Plants have also life and they also respire for their living at night. Photosynthesis do not occur at night.
