Use your calculator to get Taking the reciprocal and rounding to 1 significant figure, we get R (^) eq = 4 Ω. ...

Finally, we know that the voltage across R 2 equals the voltage across R 3 , because these resistors ...

• First, enter all the given information into your chart. If resistors haven’t already been given ...

We will follow the steps for using Kirchoff’s loop rule: • Arbitrarily choose a direction of curren ...

Next, we’ll choose a direction of current flow. But which way? In this particular case, you can probably ...

A light bulb is rated at 100 W in the United States, where the standard wall outlet voltage is 120 V. ...

Figure 19.7 Measuring voltage with a voltmeter. Current is the same for any resistors in series with o ...

Figure 19.9 Example of capacitors in series. When capacitors occur in parallel, you add them algebrai ...

first hooked up, the capacitor is empty—it is ready and waiting for as much charge as can flow to it. Thus ...

This is a differential equation. On the AP exam you will only rarely have to carry out the algorith ...

An inductor makes use of induced EMF (see Chapter 20 ) to resist changes in current in a circuit. If part ...

Figure 19.14 An RL circuit. Imagine that we connect the switch in the circuit in Figure 19.15 at time ...

Note that the current in an RL circuit looks much like that in an RC circuit. In fact, we can defi ...

3 . Three resistors are connected to a 10-V battery as shown in the diagram above. What is the current thro ...

Free Response: 6 . (a) Simplify the above circuit so that it consists of one equivalent resistor ...

then use P = IV, I 2 R , or V 2 /R to find power. On the other hand, there’s a quick way to reas ...

Now go back to the original circuit. We know that voltage is the same across parallel resistors. So b ...

• When capacitors are connected in series, the inverse of the total capacitance equals the sum of the inve ...
