The voltage V (volts), current I (amperes) and resistance R (ohms) of an electric circuit like the one shown here are related by the equation V= IR. Suppose that V is increasing at a rate of 4 volt/sec, while I is decreasing at the rate of - amp/sec. Let t denote time in seconds. Answer the following questions. RdV a. What is the value of ? dt (Type a simplified fraction.) dl b. What is the value of - dt (Type a simplified fraction.) dR dV dl c. What equation relates to and - ? Choose the correct answer below. dt dt dt O A. dR O B. dR V dV V dl + dt dt dt dt dt T at O C. dR 1 dV V di O D. dR 1 R IV dt = dt I dt dt = + dt dtdR d. Find the rate at which R is changing when V = 60 volts and I: 3 amp. E 2 (Type a simplified fraction.) is R increasing or decreasing? {3 Increasing {.1 Decreasing
