If you know the power rating of an appliance and the voltage of the line it is attached to you can you calculate the current used by the appliance?
If I understood your question correctly,
'If you know the power rating of an appliance and the voltage of the line it is attached to, can you calculate the current used by the appliance?'
You are looking for this equation:
I = Current (Amps)
P = Power Rating (Watts) V = Voltage (Volts) I = P/V This equation is useful when calculating the fuse rating for an appliance.
For example, and appliance rated at 2400 watts, supplied with 240 volts has a 10 amp maximum.
I = 2400/240
however, when it comes to paying for electricity, the energy is measured in units, which can be found using the equation: P = Power (kW) t = Time (Hours) Energy Used (Units) = Pt for example, an appliance rated at 2 kW used for 3 hours, uses 6 units of energy.
Units = 2*3

How can you calculate the current an appliance can use?
To calculate the current an appliance can use, divide the power rating of the appliance (in watts) by the voltage it operates on (in volts). The formula is: Current (in amperes) = Power (in watts) / Voltage (in volts). This calculation will give you the maximum current the appliance can draw under normal operating conditions.
How do I calculate wattage?
To calculate wattage, you need to multiply the voltage (V) by the current (I). The formula is: Wattage (W) = Voltage (V) x Current (I). This formula applies to electrical circuits where the voltage is known and the current is flowing.
How can you calculate current when you have volts power?
Divide Watts by Volts ; this gives you Amps.
How calculate unknown resistance?
-- Connect a source of known, small voltage across the ends of the unknown resistance. -- Measure the resulting current through the unknown resistance. -- Divide (small known voltage)/(measured current). The quotient is the formerly unknown resistance.
How to calculate the current in a circuit?
To calculate the current in a circuit, you can use Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R). The formula is I V/R. Simply plug in the values for voltage and resistance to find the current flowing through the circuit.
How can you calculate the current an appliance can use?
To calculate the current an appliance can use, divide the power rating of the appliance (in watts) by the voltage it operates on (in volts). The formula is: Current (in amperes) = Power (in watts) / Voltage (in volts). This calculation will give you the maximum current the appliance can draw under normal operating conditions.
How much current goes through a blender?
There are a number of ways to calculate that current, from which you're free to select the most convenient one. Here are a couple of them: Current = (the mains voltage)/(resistance of the appliance) Current = square root of (power consumed by the appliance/resistance of the appliance)
When computing wattage when to include power factor and square root of three?
In its simplest form the equation to calculate the wattage of an electrical appliance is: Watts = voltage x current. If the appliance is in a AC supply use the Route mean square voltage (the stated AC voltage).
How do you figure out an appliance's power consumption if you have the voltage and Frequency and Current?
You just need the voltage and the current. Watts = Amps x Volts.
How many volts in 1200 watts?
Wattage is unit of power which is the product of Voltage in V and Current in Amps. If you know the current drawn by the appliance with 1200 Watts then you can calculate the Voltage = Power/ Current. For eg. if the current drawn by the appliance is 100A then the voltage is 1200/100 i.e. 12 Volts.
If an adaptor is marked with output 12v dc and 2000mA does this mean the appliance draws 2amps when in use?
Yes and No. You have three types of adaptors: constant current with variable voltage output. constant voltage with variable current output. constant voltage with constant current output. What you are talking about is the latter. This means that the adaptor was created for a specific appliance requiring 12V/2A, which it will indeed use. Heavier appliance will not draw enough current/voltage and will malfunction. Lighter appliance will draw too much current/voltage and will overload/shortcircuit.

How many amps for 115 watts?
To calculate the amps for 115 watts, you need to know the voltage the appliance is operating at. If the appliance is operating at 120 volts, then the current would be approximately 0.96 amps (115 watts / 120 volts).
Can you calculate power by multiplying voltage and current?
Not enough information. Power = current x voltage. Since voltage can be anything, there is no way to calculate power. Time is irrelevant; though once you have the power, it can help you calculate energy (energy = power x time).
What is the voltage of an appliance that has a current of 3 amps and a resistance of 4 ohms?
12 volts.
What is the expression of the power consumed by an electric appliance fed by a DC?
Power consumed by the appliance = (DC supply voltage) x (DC current)
