6. Therefore, the other resistor must have come from his radio. From reading the back of the radio, he knows that it can safely take 1.75A of current. What must the potential difference be to run the radio? Be sure to provide mathematical evidence to support your conclusion. 7. If the radio were connected to a 100V source, predict what the result would be. Be sure to provide mathematical evidence to support your conclusion. V 8. Are all of the resistors Ohmic? Explain your reasoning in detail.
