II. Computation. Answer the following problem-solving using GRESA method. Show your solution. 1. If the resistance of an electric iron is 50 Q and a current of 3.2 A flows through the resistance. Find the voltage between two points. 2. An EMF source of 8.0 V is connected to a purely resistive electrical appliance (a light bulb). An electric current of 2.0 A flows through it. Consider the conducting wires to be resistance-free. Calculate the resistance offered by the electrical appliance. 3. A 110-volt wall outlet supplies power to a strobe light with a resistance of 2200 ohms. How much current is flowing through the strobe light? III. IDENTIFICATION: Identify each as Series or Parallel Circuit. Justify your answer.
