If in the circuit, power dissipation is $150 \mathrm{~W}$, then $R$ is (AIEEE, 2002) Fig. 7.35 a. $2 \Omega$ b. $6 \Omega$ c. $5 \Omega$ d. $4 \Omega$
(II) $(a)$ Determine the equivalent resistance of the "ladder" of equal $125-\Omega$ resistors shown in Fig. $40 .$ In other words, what resistance would an ohmmeter read if connected between points $A$ and $B ?$ (b) What is the current through each of the three resistors on the left if a 50.0 -V battery is connected between points $\mathrm{A}$ and $\mathrm{B} ?$
The circuit above has two resistors in parallel. The first, $R_{1},$ will have its resistance steadily increased. The second, $R_{2},$ will have a constant resistance of $R_{2}=4 \Omega .$ Which of the following graphs correctly depicts the total resistance of the circuit, $R_{T},$ as a function of $R_{1} ?$ (A) see figure (B) see figure (C) see figure (D) see figure
