A typical hair dryer draws around 10-15 amps when operating at its highest setting. It is important to check the specific amperage rating of the hair dryer you are using to ensure it is compatible with the electrical circuit you are using.

Most residential dryers run off a 30A 240V outlet. Indiviually their power ratings will vary, but they shouldn't draw more than 5.7kW. The typical dryer weighs something over 100 pounds to something under 150 pounds. Kind of a big window, but without specifics....

The current for vacuum suction can vary depending on the model and design of the vacuum cleaner. Typically, household vacuum cleaners use motors that draw between 5-12 amps of current. Commercial or industrial-grade vacuum cleaners may draw higher currents. It is important to check the specifications of the specific vacuum cleaner you are using to determine its current requirements.

The current drawn by a kettle can vary based on the power rating of the kettle. Typically, a kettle in the range of 1500-2000 watts would draw around 12-16 amps of current when operating at full power.

When an electric drill draws high current, it is typically due to increased resistance in the drill bit or the material being drilled. This resistance causes the motor to work harder to maintain the desired speed, resulting in higher current draw. It can also be caused by a dull or inappropriate drill bit, which requires more power to penetrate the material.

Using the formula Power = Voltage x Current, we can calculate the current: Current = Power / Voltage. Plugging in the values, we get 1500W / 120V = 12.5A. So, a 1500W resistance heater would draw 12.5A of current at 120V.

It's 75/120 and the answer is in amps.

Should be ok provided you do not draw too much current.

Now this is yet another example of where a student obviously needs to pay more attention in class!! If you dare, ask your instructor. He or she isn't just there to draw a paycheck.

5500Watts/220V=25 Amps

A high watt lamp draws more current than a low watt lamp because power (watts) is the product of current and voltage. If the voltage remains constant, a higher power rating means a higher current is required to supply that power. This is in accordance with Ohm's Law, which states that current is directly proportional to power and inversely proportional to resistance.

Assuming it is also rated for 120V., yes. The wattage doesn't change with an increase or decrease in voltage. However, the current draw does. When you double the voltage a load is hooked up to, the Amperage draw (current) drops in half. Example: if a 240 volt heater draws 6 amps, it will draw 12 amps if connected to 120V. If a 120V heater draws 15 amps, it will draw only 7.5 amps when connected to 240V. But power, or wattage stays the same, regardless. And this is what is used to calculate energy usage and therefore, cost. Please note the above answer says "if it is also rated for"

A 1000 watt ballast operating at 120V would draw approximately 8.33 amps of current. This can be calculated by dividing the power (in watts) by the voltage (in volts).

The current drawn can be calculated using the formula: Power (W) = Voltage (V) x Current (A). Therefore, the current drawn would be 15W / 120V = 0.125A or 125mA.

Yes, a 130 watt fan can be plugged into a 120 volt receptacle. The current draw will be I = W/E, Amps = Watts/Volts = 130/120 = 1.08 amps.

1 amp

Treating this as an ideal resistance, voltage will be half, so current will be half. Power (which is V * I) is one fourth, so you will only draw 10W.
