The energy released by a heater which draws a current of 5A at 220V for 1min.

E ~ V × I× t( hrs)÷1000
220×5×0.0167÷60000
Is equal to 0.00030 Kwh

E(kwh)=220*5*1/60 * 1/1000

I don't understand your .0167 number.

To calculate the energy released by a heater, you can use the formula:

E = V x I x t ÷ 1000

where:
E is the energy in kilowatt-hours (kWh)
V is the voltage in volts (V)
I is the current in amperes (A)
t is the time in hours (hrs)

In this case, the heater draws a current of 5A at 220V for 1 minute, which we need to convert to hours. Since there are 60 minutes in an hour, 1 minute is equivalent to 1/60th of an hour, or 0.0167 hours.

Substituting these values into the formula, we get:

E = 220 x 5 x 0.0167 ÷ 1000

Calculating this expression, we find that the energy released by the heater is approximately 0.00030 kWh.
