A uniform wire of resistance R is cut into three equal lengths. One of these is formed into a circle and connected between the other two (Fig. E26.1). What is the resistance between the opposite ends a and b?

You have a 2.0 Ω resistor, a 3.0 Ω resistor, a 6.0 Ω resistor, and a 6.0 V battery. Draw a diagram of a circuit in which all three resistors are used and the battery delivers 9.0 W of power.

What is the equivalent resistance between points 1 and 2 in FIGURE EX28.27?

Draw a circuit diagram for the circuit of FIGURE EX28.2.

At time t = 0, the switch in the circuit shown in Fig. 30–30 is closed. After a sufficiently long time, steady currents I₁, I₂, and I₃ flow through resistors R₁, R₂, and R₃, respectively. Determine these three currents.

When two resistors are connected in series, which physical quantity must be the same for both resistors?

If three resistors with resistances $R_1$, $R_2$, and $R_3$ are connected in series, what is the equivalent resistance of the group?

Three resistors with resistances $R_1$ = $2$ $\Omega$, $R_2$ = $4$ $\Omega$, and $R_3$ = $6$ $\Omega$ are connected in series. What is the equivalent resistance of the resistor network?
