Given:
U = 220 Volts – the voltage for which the electric cooker is designed;
R = 75 Ohm – resistance of an electric hotplate
It is required to determine I (Ampere) – the current in the electric stove.
To determine the current strength in an electric stove, you must use the following formula (Ohm’s law):
U = I * R, hence:
I = U / R = 220/75 = 2.9 Amps.
Answer: the current in the hotplate is 2.9 amperes.
