6 . Draw a circuit diagram showing a heater with a resistance of 6 n. and a potential difference source of 24.0 V. a. Calculate the current through the resistance b.What thermal energy is supplied by the heater in 10 seconds ? (HINT use the equation E = IZRt to determine energy ) 7.Use the circuit diagram to the right to answer the following questions a. What is the current owing through this series circuit it the total resistance is 20 (I? b. What would the voltage across each of the three bulbs be? What could you say about the brightness of each of the bulbs ? c. It two at the bulbs had a total resistance of 15 (I, what would the resistance of the third bulb be ? d. What would be the current owing through the circuit be is the voltage source was 6.0 V. and each of the lamps had a resistance of 2 Q? 24 V
