What is the resistance of a 60W 200v electric lamp?
R = 960 ohms If the operating voltage is 200 V.
How much current flows through a 60W 240V bulb?
The correct answer is 0.25 A. Given power consume by a bulb (P) is 60 W and source (V) is 240 V. We know, Current (I) = P V = 60 240 = 0.25 A. So, the current drawn by the bulb will be 0.25 A.
What is the meaning of 240V 60W?
240V refers to the voltage the bulb is rated at. It is expecting 240V AC to power it. 60W refers to the power the bulb will draw when powered with it’s rated voltage.
What is meant by the statement that the power of electric bulb is 60W?
60W is the power rating of the bulb which means that it will consume 60 Joules of energy every second. …
What do you mean by the statement that a bulb is marked as 60 W 220 V?
60 W,220 V means the power of the bulb is 60 W i.e., 60 joules of electrical energy is consumed in one second, if it is given a potential difference of 220 V.
What do you mean by the statement a bulb is rated as 60w 220V?
Answer: A 60 Watt 220V bulb means that it will consume 60 Watts when the voltage across it is 220V. In such a case the current flowing through it will be given by I= W/V = 60/220 = Amperes.
What is meant by 240 V?
An electrical appliance which is marked 240V, 1200W means that the electrical appliance will consume 1200J of energy in every second if the potential difference across it is 240V.
What does the watts on a bulb mean?
Watts measure the amount of electricity used and Lumens determine the ‘brightness’ of a bulb. The ideal combination being: LOW WATTAGE + HIGH LUMEN = BRIGHT ENERGY EFFICIENT LIGHT BULB.
What is the power of electric bulb?
The power of an electric bulb is 60 W.
What do you mean by bulb rating?
An electrical appliance such as electric bulb, geyser etc. is rated with power (P) and voltage (V) which is known as its power rating. For example: If an electric bulb is rated as 50W-220V, it means that when the bulb is lighted on a 220 V supply, it consumes 50 W electrical power.
