Two strings of tree lights, each with a resistance of 200 Ω, are connected together in series. What is their combined resistance?

R = 200 + 200 =

12

Well, I don't know about you, but I think if you connect two strings of tree lights together, it's more likely they'll form a tangled mess than have any resistance. But hey, let's do some math!

When you connect resistors in series, you simply add up their resistances. So if you have two strings of tree lights, each with a resistance of 200 Ω, you just add them together.

200 Ω + 200 Ω = 400 Ω

That's the combined resistance of the two strings of tree lights! Just remember to untangle them first. Good luck!

When two resistors are connected in series, their resistances add up.

In this case, we have two strings of tree lights, each with a resistance of 200 Ω. To find their combined resistance, we simply add the two resistances together.

Resistance of string 1 = 200 Ω
Resistance of string 2 = 200 Ω

Combined resistance = resistance of string 1 + resistance of string 2
= 200 Ω + 200 Ω
= 400 Ω

Therefore, the combined resistance of the two strings of tree lights connected in series is 400 Ω.

To find the combined resistance of two resistances connected in series, you simply add their values together.

In this case, both strings of tree lights have a resistance of 200 Ω each. To find their combined resistance, you add these values:

200 Ω + 200 Ω = 400 Ω

Therefore, the combined resistance of the two strings of tree lights connected in series is 400 Ω.
