The power of a small electric motor is (...

The power of a small electric motor is `(1)/(8)` HP . If it is con-nected to 220V supply line , how much current will it draw ? If the motor runs for 80 h , what will be the cost for BOT Unit is Rs 0.7 ?

Text Solution

Verified by Experts

Power , `P=(1)/(8)HP=(1)/(8)xx746W`
Accoding to the relation , `P = VxxI`
we have , `P=(1)/(8)HP=(1)/(8)xx746W`
Number of BOT units `=(1)/(8)xx746xx80xx(1)/(1000)`
`therefore"Cost"=(1)/(8)xx746xx80xx(1)/(1000)xx70" paise"` = Rs. 5.22 (approx.)
