Determine the current strength in the electric kettle connected to the 220V network if the resistance of the filament during the kettle operation is approximately 120V.
According to Ohm’s law, the current in an electric kettle will be directly proportional to the voltage in the network and inversely proportional to the resistance of the material from which the electric kettle’s filament is made.
I = U / R, where I is the current in the electric kettle (A), U is the voltage in the network (U = 220 V), R is the resistance of the filament (R = 120 Ohm).
Let’s calculate the current in the electric kettle:
I = U / R = 220/120 = 1.83 A
Answer: The current in the electric kettle is 1.83 A.
