The electric hob is included in a 220V circuit. Resistance of a spiral of a tile 73 Ohm. Determine the current flowing in a spiral.
Initial data: U (voltage in the circuit to which the electric cooker is connected) = 220 V; R (coil resistance) = 73 ohms.
The current strength in the spiral of the tile is determined by the formula: I = U / R.
Calculation: I = 220/73 ≈ 3 A.
Answer: The required current strength in the spiral of the taken electric hotplate is 3 A.
