Electric stoves typically have a knob that controls the heat output by adjusting the power level. Turning the knob clockwise increases the power level, and turning it counterclockwise decreases the power level until it reaches the "off" position (usually denoted by "0" or "Off").
If your stove is currently set to level 4, and you turn the knob counterclockwise to 5 and then to 0 (Off), it should effectively turn off the stove. However, it's important to note that the numbers on the knob usually represent heat levels rather than actual power settings. The specific number-to-power relationship can vary between stove models.
In most cases, turning the knob counterclockwise from 4 to 5 will not increase the power level but rather decrease it to a lower setting. Then, turning the knob from 5 to 0 (Off) should turn off the stove completely.
Keep in mind that the best way to ensure the stove is off is to check the indicator lights or physically verify that there is no heat emanating from the burners. Additionally, always follow the manufacturer's instructions and safety guidelines for your specific electric stove model.
