What is the meaning of the statement that _an electric bulb is rated 1...
Meaning of the statement:
An electric bulb that is rated 100 watts and 220 volts refers to the specifications of the bulb in terms of its power consumption and the voltage it requires to operate efficiently. It provides information about the amount of electrical power the bulb consumes and the level of voltage it can handle.
Power consumption:
The rating of 100 watts indicates the power consumption of the electric bulb. Power is the rate at which energy is consumed or transformed. In this case, the bulb consumes 100 watts of electrical power when it is in operation. This power consumption determines the brightness and intensity of the light emitted by the bulb. A higher wattage generally indicates a brighter light.
Voltage requirement:
The rating of 220 volts indicates the voltage required to operate the electric bulb efficiently. Voltage is the electrical potential difference that enables the flow of electric current. The bulb is designed to operate optimally at 220 volts, which means that it requires a power supply with a voltage of 220 volts to function properly. If the voltage supplied is significantly higher or lower than 220 volts, it may result in inefficient operation or even damage to the bulb.
Relationship between power and voltage:
The relationship between power and voltage can be understood using the formula: power (in watts) = voltage (in volts) × current (in amperes). In this case, the given power rating of 100 watts and the voltage rating of 220 volts do not provide information about the current. However, it is important to note that the current flowing through the bulb will be determined by the power and voltage ratings.
Summary:
In summary, an electric bulb that is rated 100 watts and 220 volts consumes 100 watts of electrical power and requires a voltage of 220 volts to operate efficiently. The power rating determines the brightness of the light emitted by the bulb, while the voltage rating indicates the level of electrical potential difference required for its proper functioning. It is important to ensure that the bulb is connected to a power supply that matches its voltage rating to avoid any damage or inefficient operation.
