The voltage remains the same. What happens when bulb is removed? Think about the resistance of each bulb, and the relationship between voltage, current and resistance.chemistrykid said:Q: Two bulbs x and y are connected in parallel to a new dry cell.

b) halve
c) remain the same
d) become 0
A: a? The current from the first branch would go into the second branch?
It depends on the battery chemistry. But as with many subtle multiple-choice questions, there is only one best answer in the choices given (as Astro has indicated).chemistrykid said:Q: Two bulbs x and y are connected in parallel to a new dry cell.

In a parallel circuit, each light bulb has its own separate path to the power source. This means that each light bulb receives the same amount of voltage, allowing them to all shine at the same brightness. If one bulb burns out, the rest will still continue to work.
Yes, you can mix different types of light bulbs in a parallel circuit. This is because each light bulb has its own individual connection to the power source, so the type of bulb does not affect the others.
If you add more light bulbs to a parallel circuit, the total resistance of the circuit will decrease. This means that the current will increase, and each light bulb will shine less brightly. It is important to make sure that the total resistance does not become too low, as this can cause the circuit to overload and potentially cause a fire.
The total resistance in a parallel circuit is calculated by adding the reciprocals of each individual resistance and then taking the reciprocal of the sum. For example, if you have three light bulbs with resistances of 2 ohms, 4 ohms, and 6 ohms, the total resistance would be 1/(1/2 + 1/4 + 1/6) = 1.2 ohms.
Yes, you can use a dimmer switch in a parallel circuit with light bulbs. The dimmer switch will work for all of the light bulbs in the circuit, allowing you to adjust the brightness of all the bulbs at once. However, it is important to make sure that the dimmer switch can handle the total wattage of all the light bulbs in the circuit.
