According to the question,
Given that
V = 220 V
I = 8 A
, t = 2 h
E = VIt
We know that
E = 220 × 8 × 2
E = 3520 Wh
E = 3.52 kWh
Therefore, Cost of 3.52 kWh energy is ₹ 4.50 × 3.52 kWh= ₹ 15.84
An electric toaster draws current 8 A in a circuit with source of voltage 220 V. It is used for 2 h. Find the cost of operating the toaster if the cost of electrical energy is ₹ 4.50 per kWh
