What is wattage of an instrument if you only know it is 220V50Hz?
To determine the wattage of an instrument with a voltage of 220V and a frequency of 50Hz, you need to know the current it draws (in amperes). Wattage can be calculated using the formula: Wattage (W) = Voltage (V) × Current (A). Without the current value, the wattage cannot be determined.
How much units current take to run table fans?
It depends on the wattage the fan draws. A simple way to work it out is to use a simple formula. Find where it tells you the wattage and then devide by the house hold voltage and that will give you how much current is being used in amps
A power drill runs at a voltage of 120 V and draws a current of 4 A. What is the wattage of the drill?
The formula you are looking for is W = A x V. Watts = Amps x Volts.
Does a 25 watt light bulb draw more current than a 60 watt light bulb?
No, a higher wattage INCANDESCENT light bulb uses more current than a lower wattage INCANDESCENT light bulb. Some CF and LED bulbs are rated by the amount of light that an incandescent bulb would produce, but they are also rated by the wattage that they use.
How much does it cost to run each appliance for one week?
Different appliances have different wattage draws. Without knowing the wattage of the appliance, an answer can not be given.

A power drill runs at a voltage of 120 V and draws a current of 4 A What is the wattage of the drill?
The wattage of the drill can be calculated by multiplying the voltage (120 V) by the current (4 A). Wattage = Voltage x Current Wattage = 120 V x 4 A = 480 watts. Therefore, the wattage of the drill is 480 watts.
How many watts is an 18volt power tool?
To determine the wattage of an 18-volt power tool, you need to know its amperage (current). Wattage is calculated using the formula: Watts = Volts × Amps. For example, if the tool draws 5 amps, the power would be 90 watts (18 volts × 5 amps). Without the amperage, you cannot calculate the exact wattage.

A laptop computer draws 5 A of current with a voltage of 19 V which is the power used by the computer?
(current * voltage) / psu efficiency (5 amps * 19 volt) / ~0.8 = ~118 watts
How many amps does a block heater draw?
To answer this question the wattage of the block heater must be stated. Amps = Watts/Volts.
What is the current AMP of a 220V rice cooker?
The amps it draws depends on how big it is. Typically 2-12 amps. Check for a manufacturer's plate that shows the wattage Most of the load in a rice cooker is a resistive heating element, so the amperage will be quite close to the wattage divided by the voltage (220 here).
Do higher watt inverters drain batteries more than lower watt?
The inverter draws little current on its own. It is the load that is connected to the inverter. If there were no load on the inverter you could use an ampmeter to determine the no load current. One thing to consider is that a higher wattage inverter would have larger gauge wire which is of lower resistance. This could make the no load current lower for the higher wattage inverter. Bottom line is you would have to measure or have a specification on the no load current.
A heater draws 8.70 amps on a 110 volt line What is its wattage rating?
Power = Voltage x Current P=V.I Power (in Watts) = 110V x 8.70A = 957W (Appx. 1kW) - Neeraj Sharma
