0.9 power factor add kar sakte ho Ghar ke ander

Power factor is not typically considered when calculating the current for a single-phase load in designing a Miniature Circuit Breaker (MCB) for several reasons: Simplification: MCBs are primarily designed to protect against overcurrents and short circuits. Considering power factor would add complexity to the design calculations without significant benefits for single-phase loads. Unity Power Factor: Many single-phase loads, such as resistive heaters and lighting, have a power factor close to 1 (unity power factor). In these cases, the apparent power (VA) is approximately equal to the real power (Watts). Therefore, using the current based on the real power simplifies calculations. Limited Impact: For most residential and small commercial applications, the impact of power factor on the current is not significant enough to warrant special consideration when selecting an MCB. Focus on Overcurrent Protection: MCBs are primarily intended to protect against excessive current that can lead to overheating and fires. Their main purpose is to disconnect the circuit when the current exceeds a safe threshold, regardless of the power factor. However, in industrial or commercial settings where power factor correction is important, and where non-linear loads like motors and electronic equipment are common, power factor may play a role in electrical system design and protection. In such cases, other protective devices or specialized equipment might be used to address power factor issues.

Yes, u have consider the power factor.

My question is same

He should be assume pf 0.8

Oven, which ampier MCB I have to select.

Nhi function alg hota h. Par dono overload 32 ampere he hoga..apko detail video chiye ho too comment karke jarur btaye.

Nutaral ak return provide krne ka kam krta hai . Islye nutral me current and voltage 0 hota hai

बहुत मजे ले रहे हो😂😂🤣😋🤣😂 स्विच भी नहीं आता 1A का तो

@@Tech_Gaurav video me bataya hai ki 1 amp ki mcb aati hai aap video me dekh ke tasalli kar sakte hai 4:28 minutes pe

Me bhi confused hun ki 1 amp ki mcb aati hai ya nahi
