Power = Voltage*Current. Multiply the current and the voltage. Keep your units in mind. If your voltage is Volts, and your current is in Amps, your power will be in Watts. If you are using milliamps, your power will be in milliwatts. You can also use P=I2*R. The current squared, mulitplied by the resistance of the circuit. Or P=V2/R, the voltage squared divided by the resistance of the circuit. The last two of these can be derived from the basic equation V=I*R and P=V*I. Here's a little helper for you too. "Twinkle twinkle little star, power equals I squared R".

How do you find the efficiency of an electrical device?
To find the efficiency of an electrical device, you can use the formula: Efficiency (%) = (Output Power / Input Power) × 100. Measure the input power, typically in watts, that the device consumes and the useful output power it provides. Efficiency indicates how well the device converts electrical energy into useful work, with higher percentages indicating better performance.
How do you calculate the amount of heat generated from electrical home appliances?
The amount of heat generated by electrical home appliances can be calculated using the formula: Heat (in watts) = Power (in watts) × Time (in hours). First, determine the power rating of the appliance, usually found on the label or in the manual. Multiply this power rating by the duration the appliance is used to find the total energy consumed, which can be converted to heat energy since most electrical energy converts to heat in resistive appliances.
Rate at which electrical energy is converted to another type of energy?
The rate at which an appliance takes energy from the electrical outlet and spinsthe electric meter is the "power" shown on the data label, usually on the backor the bottom of the appliance.The rate at which it actually converts the energy into the form required to do itsjob is also a "power" figure. This one is always less than the power taken fromthe wall outlet, and is not always stated or marked on the appliance.A couple of cases where it is clearly stated:-- Microwave Oven: " 600 Watts of Cooking Power "The microwave oven is using perhaps 1,500 to 2,000 watts from the electric company,converting some of it into radio waves (with less than 100% efficiency), and delivering600 watts of microwave radiation to the cooking chamber.-- Blow Drier: " 1,250 Watts of Drying Power "The blow drier is using perhaps 1,500 watts from the electric company, anddelivering useful energy at the rate of 1,250 watts, in form of a hot coil anda strong little fan motor to blow air across the coil.But on an electric stove, furnace, blender, food processor, fan, telephone, TV,computer, vacuum, washer, dryer, etc., you can find the power consumptionmarked somewhere on it, but it's not clear exactly where that power goes.
How many amps does 6000 watts pull?
There are zero amps in 6600 watts. Watts are the product of amps times volts. W = A x V. To find amperage use the following equation, A = W/V, so as you can see a voltage value is needed in the equation to result in an amperage.
How do you protect two power in one circuit?
If the question means "two loads in one circuit" then the load currents have to be added together. The breaker that protects the circuit is sized for the total loading of the circuit. These two loads of course will be in parallel with each other. Find the wattage of the two loads if the amperage is not available. The equation is W = A x V. Watts = Amps x Volts. Once the total amperage of the circuit is found select the correct wire size for that amperage. The breaker protects the wire size so then select the proper breaker for that wire size.
What is the formula to find watts?
There are several ways to find watts; volts x amps = watts or resistance (ohms) divided by amps squared or volts squared divided by amps. You can search for Ohm's Law to find examples of these different methods and sample calculations.
How to find watts in physics and what is the formula for calculating it?
To find watts in physics, you can use the formula: Watts Volts x Amps. This formula calculates power, which is measured in watts, by multiplying the voltage (in volts) by the current (in amps) flowing through a circuit.
How do you find power in a circuit?
Power in a circuit can be calculated by multiplying the voltage (V) across a component by the current (I) flowing through it. The formula for power is: P = V x I. It is measured in watts (W).
How many volts are in 15 watts?
That would depend on how many amps are drawn at 1.5V. A watt is a measure of power. Electrical power is determined by electrical potential (voltage) and electron flow (current). Power = Voltage * Current To find your answer, you need to know the current consumption of your load to know how many watts it is consuming. If you are trying to figure out how many watts can be provided from a source, say from a 1.5V battery, you would need to know the current output of the battery (which is usually provided in Ah, which tells you how many amps it can produce in one hour).
How many watts in 10 amps?
Watts and amps measure different things, and they cannot be converted as asked. Watts measures power. Volts measures voltage and amps is a measure of current. The three electrical parameters are related by this formula: Power (watts) = volts times amps. If you know the voltage, then you can find the watt-to-amp ratio.
Where can you find the power rating of an electrical appliance?
Normally the power rating of an electrical appliance can be found on its 'Rating Plate' or, if there isn't one, use the following formula W = A x V, where W = watts, A = current and V = voltage.
How do you find the current draw of an electrical circuit if you do not know the voltage and wattage of the device?
Basically if you know the Voltage supply and the power used by an appliance then you use the formula for power which is Power = Volts x Amps. Rearrange so Amps (current) = Power / Volts If power was 2400 Watts and Volts was 240 the Current would be 2400 / 240 = 10 Amps
How do you find the efficiency of an electrical device?
To find the efficiency of an electrical device, you can use the formula: Efficiency (%) = (Output Power / Input Power) × 100. Measure the input power, typically in watts, that the device consumes and the useful output power it provides. Efficiency indicates how well the device converts electrical energy into useful work, with higher percentages indicating better performance.
What total ampere in 736watts used in 8 hours?
You cannot find ampere from watts (power) and time, alone. To find amperes (electrical current) from power, you also need to know the voltage, then:Current = (Power) / (voltage), or Amperes = Watts / Volts.You can get energy (measured in kilowatt-hour) from the information you have:736 watts is 0.736 kW, then multiply by 8 hr to get 5.888 kWh
How much wattage is available in a 15amp breaker?
A 15-amp breaker can handle a maximum load of 1800 watts (15 amps x 120 volts). However, it is recommended to only load a circuit up to 80% of its capacity, so in practice, you should only use up to 1440 watts on a 15-amp breaker.
75 percent is equal to how many watt's?
To convert a percentage to watts, you need more information. Watts is a unit of power, and percentages are not directly convertible to watts without knowing the total power or another related quantity.
How to find the neutral wire in an electrical circuit?
To find the neutral wire in an electrical circuit, you can use a voltage tester or a multimeter. Turn off the power to the circuit, then test each wire to see which one has a voltage reading close to zero. This wire is the neutral wire. Remember to always follow safety precautions when working with electricity.
