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.

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?
Yes, you can calculate the current used by the appliance by dividing the power rating of the appliance by the voltage of the line it is attached to. The formula to calculate current is: Current (A) = Power (W) / Voltage (V). This will give you the amount of current flowing through the appliance when it is operating.
Which wire in a cable is at or near to 0V and conducts an electric current whenever the appliance is switched on?
The wire that is at or near 0V and conducts an electric current whenever the appliance is switched on is the neutral wire. This wire completes the circuit and provides a return path for the current to flow back to the source.
An electric iron is marked 240 voltagen 1200 w calculate the current flow through the electric iron?
To calculate current flow, use the formula: Current (I) = Power (P) / Voltage (V). Substituting the given values, the current flowing through the electric iron would be I = 1200W / 240V = 5A.
An electric appliance draws 1.5 amperes of current when it is connected to a 24-volt source - What is the resistance of this appliance?
The resistance of the appliance can be calculated using Ohm's Law: Resistance (R) = Voltage (V) / Current (I). In this case, R = 24V / 1.5A = 16 ohms.
How calculate unknown resistance?
To calculate an unknown resistance, you can use Ohm's Law, which states that resistance (R) equals voltage (V) divided by current (I). You can measure the voltage across the unknown resistance using a multimeter and the current flowing through it using an ammeter. Then, you can divide the voltage by the current to calculate the resistance.
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)
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?
Yes, you can calculate the current used by the appliance by dividing the power rating of the appliance by the voltage of the line it is attached to. The formula to calculate current is: Current (A) = Power (W) / Voltage (V). This will give you the amount of current flowing through the appliance when it is operating.
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).
What will happen to an appliance if the fuse rating is less than the current an appliance needed?
If the fuse rating is less than the current an appliance needs, the fuse will likely blow or burn out. This is because the fuse is designed to protect the appliance from overheating or catching fire by interrupting the circuit when the current exceeds the fuse rating. It is important to always use a fuse with a rating that matches the current requirements of the appliance.
What is really meant when you say an appliance use up electricity?
the current disappears!!:))
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.
If a 120 volt current is protected by a 25 amp circuit breaker What is the largest number of watts an appliance can safely use?
The largest number of watts an appliance can safely use on a 120V circuit protected by a 25A breaker is 3000 watts. You calculate this by multiplying the voltage (120V) by the amperage (25A). This gives you a maximum power capacity of 3000 watts on this circuit.
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).
How does a fuse wire save an appliance from high electric current?
A fuse link will melt and interrupt the flow of current to the appliance before it can get high enough to damage the appliance or wiring.
How can you calculate a current stock pricing?
use a calculator!
Why you use inductor?
we use the inductor because it helps the circuit to have an appropriate amount of current, so that the circuit in the appliance will say longer.
Calculate 120Volt 15 amp appliance kWh?
To calculate the kWh usage of a 120V 15A appliance, you can use the formula: Power (in watts) = Voltage x Current. For the given appliance, power = 120V x 15A = 1800 watts. To convert watts to kilowatt-hours (kWh), divide by 1000: 1800 watts / 1000 = 1.8 kWh. Therefore, the appliance uses 1.8 kWh of energy per hour.
