An electric device consumes of energy in min, while operating at . Calculate the current drawn by the device.
Step 1: Given data,
Step 2: Find the current drawn by the device,
Energy consumed in terms of the power and time is,
……(1)
The power in terms of voltage and current is,
……..(2)
Thus, from equations (1) and (2),
Substituting the known values,
From the equation, the value of the current is,
Thus, the current drawn by the device is .
