1.9445 k-ohm
1.6665 k-ohm
2.3335 k-ohm
Obviously some rounding errors, but if my methods were correct, it should be close enough.
(Also, finally some math. I can finally get into the game!)
It's been a while since I calculated the answers, but I think those are right. Your turn!

Will post in the evening, I'm at a math competition rn
West High '19
UC Berkeley '23

Go Bears!

So lets restart this,

1. Image What is circuit called, and what is its purpose?
2. Name three waveforms of Alternating current.
3. Name 3 methods of producing static imbalance.

2. Name three waveforms of Alternating current.
3. Name 3 methods of producing static imbalance.
1. A Wheatstone Bridge and it's purpose is to find the mystery resistor, Rx
2. Sine waves, triangular waves, and square waves
3. Rub a balloon on your hair, rub a balloon on a furry carpet, rub a balloon on a wool jacket
Nothing for now...
Keep on going :!:

All good, but for number three i was looking for like contact, heat induced, pressure induced

Ohhh okay :)

How do you find the strength of an electromagnetic field?

What would be the strength of the magnetic field if the electromagnet was 200 cm, has 10 amps running through it, and has 400 coils?

Reviving... what does Coulomb's law state?
The magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them.
