An electric heater rated $600\, W$ operates $6$ hours per day. Find the cost to operate it for $30$ days at ₹ $3.00$ per unit.
An electric heater rated $600\, W$ operates $6$ hours per day. Find the cost to operate it for $30$ days at ₹ $3.00$ per unit.
Given $\quad P=600 W$
$t=6 h$ per day
days $=30$
Energy consumed $= P \times t=600 \times 6 \times 30$
$=108000 W h =108 kW h$
Therefore, cost of operation
$=108 \times 3=$₹ $324$
