PHY2061 R. D. Field Problems Chapter 31 Page 1 of 3 R 1 = 4 24 V R 2 = 12 R 0 = 3 Chapter 31 Problems Problem 1: How much current passes through the 1 resistor in the circuit shown in the Figure ? r r r A B r r r r r r r r R r Problem 2: Consider the infinite chain of resistors shown in the Figure . Calculate the effective resistance, R , ( in Ohms ) of the network between the terminals A and B given that each of the resistors has resistance r = 1 Ohm . Problem 3: Consider the circuit consisting of an EMF and three resistors shown in the Figure . How much current flows through the 4 resistor ( in Amps )? Problem 4: A constant power P is supplied to a transmission line of resistance R by a power station. If the power dissipated in the transmission line is 200 Watts when the power station delivers an EMF of 10 Volts , how much power is dissipated in the transmission line ( in W ) when the power station delivers an EMF of 20 Volts (assuming the same power is supplied in both cases) ?
