## Answer to relevant Questions

(a) For the circuit show in Fig. 18.10, traverse loop 3 opposite to the direction shown, and demonstrate that the resulting equation is the same as that obtained if you had followed the direction of the arrows. (b) Repeat ...Apply Kirchhoff’s rules to the circuit in Fig. 18.36, and find (a) The current in each resistor and (b) The rate at which energy is being delivered to the 8.0-Ω resistor 8.0. In a flashing neon sign display, a certain time constant is desired. (a) To increase this time constant, you should (1) increase the resistance, (2) decrease the resistance, (3) eliminate the resistor. Why? (b) If a 2.0 s ...(a) In how many different ways can three 4.0-Ω resistors, be wired: (1) three, (2) five, or (3) seven? (b) Sketch the different ways you found in part (a) and determine the equivalent resistance for each. Suppose you are using a drill that is incorrectly wired as in Fig. 18.22a, and you make electrical contact with an ungrounded metal case. (a) Explain why this is a dangerous situation for you. (b) Estimate the current in ...Post your question
