Hello, first i want to thank you, you really help me alot last time.
Now i have this 2 problem.
The electrical disc is connected to a 230 V mains voltage and through it a 9.5 A current is passed. How long
can it be used for 9 euros? Suppose that electricity costs 10 cents / kWh.
When the computer is connected to 230 V, a 0.9 A current passes through it. How much is it
use for 1 hour? Suppose that electricity costs 10 cents / kWh.
