AP Physics 2 - Resistors and Resistance

1

You have 3 resistors in parallel with each other. What can you say for certain about the total resistance of the circuit?

2

You have two resistors in series, with the pair being in parallel with another resistor. What can be said for certain about the total resistance?

What is the total resistance of the circuit if the values of the resistors are as follows?

$\begin{align*} A&=2\Omega \ B&=2\Omega \ C&=4\Omega \ D&=3\Omega \end{align*}$

Resistances:

$\begin{align*} A&= 1\Omega\ B&= 2\Omega\ C&= 3\Omega\ D&= 4\Omega\ E&= 5\Omega\ F&=6\Omega \end{align*}$

If the circuit above is connected to a battery, what is the total power output of the system?

5

Suppose a circuit consists of a battery connected to four resistors, all of which are connected in parallel. If a fifth resistor is added in parallel to this circuit, how will the current in the other four resistors change?

Resistors

The circuit in the figure has a battery providing a potential. The resistors have resistances of $R_{1}=3\Omega$ , $R_{2}=6\Omega$ , $R_{3}=8\Omega$ . Find the voltage drop across $R_{3}$ .
