Question

Using Kirchhoff's rules, find the following. (Ez = 70.4 V, &z = 61.5 V, and ag = 79.4 V.) 4.00 12 E R ES R, 3.00 k. 2.00 K12 a R (a) the current (in mA) in each resistor shown in the figure above mA IR IR 2 ma IR 3 mA (b) the potential difference between points c and f(Give the magnitude of your answer in volts and select the point of highest potential.) magnitude of potential difference V point at higher potential ---Select- (c) What If? If all of the resistors in the circuit were decreased in value by a factor of 1,000, would the current in each resistor simply increase by a factor of 1,000? Explain your answer.
