How Many Appliances, One Plug? (Kitne Appliance, Ek Plug?)
Adults · Everyday science · Current, power and the extension board
About 8 minutes · taught by Arjun Bhaiya with Chintu the robot · Hinglish or English
Everyday electricity for adults: how much can one extension board safely take? Arjun Bhaiya connects the watts printed on common appliances to the current they draw at home voltage (about 230 V), using I = P ÷ V.
Learners load a virtual extension board with appliances, compare the total current with the board's rating, and see what overload means. It also clears up a common belief: that a higher-watt appliance takes a higher voltage. Wiring work is always for a licensed electrician.
Arjun Bhaiya ke saath extension board pe appliances lagao aur samjho ki watt, current aur board ki rating ka kya rishta hai.
