CHAPTER 19 Circuits 1 . An electronics manufacturer needs a 1.2 Ω resistor for a phone it is ...

(A) Both A 1 and A 2 increase. (B) A 1 increases, and A 2 stays the same. (C) A 1 increases, ...

(E) 4 . The circuit shown in the figure has a battery with an emf of 24 V and an internal resi ...

When the switch is closed, the two resistors in parallel on the right combine to give R . When added in ...

CHAPTER 20 Magnetism IN THIS CHAPTER Summary: Magnetic fields produce forces on moving charges; moving charges, ...

Induced EMF: Induced EMF for a rectangular wire moving into or out of a magnetic field: ε = BLv Time constant ...

A magnet creates a magnetic field. (See Figure 20.3 .) Unlike electric field lines, which either go ...

Supposedly, the drawing in Figure 20.4a is intended to look like the tip of an arrow coming out of a page ...

Here’s another example. What does the magnetic field look like around a wire in the plane of the ...

to the magnetic field, then you will need to throw in this extra “sin θ ” term. Right-hand rule: ...

Finally, we solve for direction using the right-hand rule. We point our hand in the direction that the ...

Now, a wire’s field cannot produce a force on itself. The field that we drew is caused by the left ...

the electric field. By the time it gets to the end of the electric field, it has acquired a high velo ...

Figure 20.9 Loop of wire in the plane of a magnetic field. No field lines go through the loop. ...

ε is the induced EMF, N is the number of loops you have (in all of our examples, we’ve only had one loop ...

region, there will no longer be a changing flux, because no matter where it is within the region, the same ...

We say this from personal experience. First, when using a right-hand rule, use big, easy-to-see gestures ...

outside the wire; inside the wire, the field increases linearly from zero at the wire’s center. A ...
