Four resistors are connected in a circuit with a battery of unknown emf, as shown below. The battery is ideal, so it has no internal resistance. The current in the 30 N resistor is 100. milliamps. Note that you should be able to do this problem without a calculator. 20 Ω 60 Ω 30Ω 80 Ω (a) Calculate the current in the 60 N resistor. 50 (b) Calculate the current in the 80 N resistor. 150 mA (c) Calculate the power dissipated in the 20 N resistor. 0.45 (d) Calculate the current in the battery. 300 X mA
