Yes. In North America household power is 120/240V at 60Hz and 45 Watts means it will only draw 0.375 Amperes. So it can safely be used
What else can I help you with?
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.
What does the power rating of an electrical appliance mean?
The power rating of an electrical appliance represents the rate at which the appliance uses electrical energy. It is typically measured in watts and indicates how much electricity the appliance consumes when it is in use. Higher power ratings suggest that the appliance uses more energy.
Why does my house have no power?
Your house may have no power due to a power outage in your area, a tripped circuit breaker, a blown fuse, a problem with the electrical wiring, or a malfunctioning electrical appliance. It is recommended to check these potential issues and contact a professional electrician if needed.
What is the power of an electrical appliance?
It depends on the appliance. All appliances are required to have a 'nameplate' which contains information on their power and voltage ratings.
What does the power rating of an appliance mean?
what is the power rating of energy
Which would you use for a 250W appliance and why?
I would use a 300W power supply for a 250W appliance. It's recommended to have a power supply that can handle more than the actual wattage of the appliance to ensure efficient operation and prevent overloading. In this case, a 300W power supply would provide enough headroom to safely power the 250W appliance.
What is the maximum power consumption of the appliance when operating at 230V 50Hz?
The maximum power consumption of the appliance when operating at 230V 50Hz is determined by multiplying the voltage (230V) by the current (in amperes) that the appliance draws. This calculation will give you the power consumption in watts.
Will the power consumed by an electrical appliance increase with a reduction of applied voltage?
Power consumed by an electrical appliance will increase with a reduction of applied voltage.
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)
When you use an electric appliance the amount of electric energy you use depends on.?
only the appliance power
What is a measure of the electric power an appliance uses?
The measure of the electric power an appliance uses is called wattage. It is typically expressed in watts on the appliance's label or specifications. The wattage helps determine the energy consumption and cost of operating the appliance.
Does an appliance use power when not on?
If it is plugged in yes.
