What may happen if you add another bulb to both of your setup Why?

When you plug in that second bulb, both will get equally dim, because you have added more resistance to your circuit, which decreases the flow of current. Adding another light bulb in series decreases the current because our battery now has more work to do! You just add all of the different resistance values together.

What happens when you add bulbs in parallel?

In a parallel circuit the current goes through separate branches. If another branch is added with another bulb, the current has an additional path to take. But, the battery (or generator) produces a constant voltage, so the current through the original bulbs does not change, and neither does their brightness.

What is the problem in connecting the bulbs in series combination?

If one electrical appliance stops working because of a serial circuit fault, then all devices will stop functioning. All electric switches will have common switches in series circuits so that they can not be switched off and on separately. The voltage will be split through all electrical devices in a series circuit.

What is the disadvantage of parallel connection?

A disadvantage of parallel circuits is that they require more wiring. Additionally, the voltage can’t be increased in a parallel circuit without decreasing the resistance in the circuit.

What happens to current when cells are connected in parallel?

Current remains same whenever measured in series. Now, if two cells are connected in parallel , currents are added . Similarly for voltage , Voltage whenever measured at parallel points are same.

Which combination is used for connecting small bulbs for decoration?

Hence, the bulbs used for decoration are always connected in series. Note: In series connection if one of the components is faulty the whole connection breaks out but in parallel connection if one component is faulty all the other component remains fully functional.

Are light bulbs brighter when connected in series or parallel?

If light bulbs are attached in parallel, the current will be divided across all of them. But if the light bulbs are connected in series, the current will be the same in all of them. Then it looks like the bulbs should be brighter when connected in series, but actually, they are brighter when connected in parallel. Why is that?

How to simplify the circuit where the light bulbs are in series?

First, we simplify the circuit where the light bulbs are in series. R series = R + R = 2R. Secondly, we simplify the circuit where the light bulbs are in parallel.

Are the Christmas lights in series or parallel?

Based on hint 1, it seems the lights are in series. Based on hint 2, it seems they are in parallel. The answer is that the lights are in series. Yup. But how can this be? How can you have one light with a broken filament and still have the other lights on? In the physics world, we call this “the magic of Christmas”. Ok, not really.

How are two light bulbs connected to identical batteries?

Two identical light bulbs are connected to identical batteries in two different ways. First they are connected in series and then in parallel. In which circuit will the bulbs shine brightly?
