By comparing R1 and R2 first bulb, i.e., bulb with rating 60W−220V offers more resistance.
Q. Which one is having lesser resistance A 2 20 volt 60 watt bulb or 220 volt 40 watt bulb?
if v is constant. Hence bulb of higher voltage will have less resistance. In other words, resistance of 60W bulb is less than the resistance of 40W bulb.

Q. Which has more resistance 100w bulb or 60W bulb?
Solution. A 60-watt bulb has a higher electrical resistance than a 100-watt bulb. Because power is inversely proportional to resistance, when the power is less, the resistance is high.
Q. How many amps is a 10 watt LED bulb?
1/12 amp
Q. Will the current in a light bulb connected to a 220V source be greater or less?
1) Will the current in a light bulb connected to a 220-V source be greater or less than when the same bulb is connected to a 110-V source? The current will be less: Current = Voltage/Resistance, so if the Voltage is halved then, there will be half as much current through the same bulb.
Q. How many amperes flow through a 60 watt bulb when 120 volts are impressed across it?
0.5 ampere
Q. Are two bulbs connected in series to a battery?
When two bulbs are connected in series with two batteries, each bulb shares the voltage drop equally. So each bulb has half the total voltage across it. Each bulb has the voltage of one battery across it. And each bulb glows the same as if it were connected to one battery.
Q. Will water flow more easily through wide or narrow pipe?
Will water flow more easily through a wide pipe or a narrow pipe? Will current flow more easily through a thick wire or a thin wire? Water will flow more easily through a wide pipe.
Q. Will current flow more easily through a thick wire or a thin wire?
The current will flow more easily through the thick wire than the thin wire. It is because the resistance of a conductor is inversely proportional to its area of cross-section. If thicker the wire, less is resistance and hence more easily the current flows.
Q. What kind of charging occurs during thunderstorms?
What kind of charging occurs during thunderstorms? Ice crystals are charged by friction and the ground is charged by induction. as warm water vapor rises in the air, it brushes against ice crystals high in the air above, producing a charge (friction). What is the primary purpose of a lightning rod?
Q. What conditions is necessary for the flow of heat?
A hot object has a higher temperature while a cold object has a lower temperature. The condition necessary for the flow of heat is temperature difference. Negative charges flow from high potential to low potential through a circuit. The condition necessary for the flow of charge is potential difference.
Q. Why is the high specific heat of water important to Earth?
A high specific heat of a substance means that a large amount of heat is required to raise the temperature of the substance. Water covers around 70% of the Earth’s surface and its high specific heat plays a very important role as it is able to absorb a lot of heat without a significant rise in the temperature.
