What happens if one of the parallel light bulbs is taken out?
The other lights in the parallel circuit do not get affected by the removal of the middle bulb. The other light bulbs have a connection with the voltage source.
What do you notice about the intensity or brightness of the bulb as you add more bulbs?
The circuit receives a higher voltage, which means that the current is more rapid and the bulb’s brightness is greater.
When a 60 W 200 V bulb is connected in series with 100 W 200 V bulb across a 200 V AC power supply which bulb will glow brighter?
When a 60 W, 200 V bulb is connected in series with 100 W, 200 V bulb across a 200 V A.C. power supply, which bulb will glow brighter? Solution: 60 Watt bulb will glow brighter then 100 Watt bulb.
Which has more resistance 100 W bulb or 60 W bulb if connected in in parallel with a supply of 220 volt?
If the voltage of two bulbs is assumed to be the same, the resistance of the bulbs equals to V/100 and V/60 respectively. Thus, it is proved that the 60W bulb has higher resistance than the 100W bulb.
Which is having more resistance a 220V 100 W bulb or a 220V 60 W bulb?
Answer: The 220V, 60W bulb has more resistance. R=220*220/100=484ohm (approx.) R=220/10=ohm (approx.
Which of the following bulbs has least resistance?
Which bulb will be the most resistant?
|1)||220 V, 100 W|
|2)||220 V, 60 W|
|3)||115 V, 100 W.|
|4)||115 V, 60 W|
Which of the following lamp will have least resistance at room temperature?
Which one of the following lamps has the lowest resistance at room temperature? (D) 25 W, 220 V. (D) Carbon. (D) 10V….105.

Does brightness of bulb depend on resistance?
The power of a lightbulb determines its brightness. P=I2R. Therefore, brightness is dependent on current and resistance. If identical bulbs have the same resistance, they will be the same brightness. When you ask to rate the brightness of identical bulbs you really need to rank their current.
