An electric device is rated 2000W, 250V. Calculate the maximum current it can take
Answer Details
The maximum current that an electric device can take can be calculated using Ohm's law, which states that the current in a circuit is directly proportional to the voltage and inversely proportional to the resistance.
In this case, the electric device is rated 2000W and 250V, so we can calculate the resistance using the power formula:
P = IV
where P is the power in watts, I is the current in amperes, and V is the voltage in volts.
Rearranging the equation to solve for I, we get:
I = P/V = 2000W / 250V = 8 A
So, the maximum current that the electric device can take is 8 A.
