Direction: Answer the following problems. Show your complete solution. 1. Complete the table. POTENTIAL DIFFERENCE = V= Q/C ENERGY = ENERGY STORED IN A CAPACITOR U =1cuz where C=4 = U= 1QV 2 2 CAPACITANCE = C = Q/V ENERGY STORED IN A CAPACITOR = U = Icv2 where C = = U = Qv 2 V 2 Capacitance Charge Potential difference Energy 0.0016 C 0.013 J 0.01 F 1.0 V 14 C 14 V 4.0x 10" F 5 J 1.0mc 100 V 11 V 2.0 J 2. Ten identical 6 AF capacitors are connected in parallel to a 240-V battery. The charged capacitors are then disconnected from the battery and reconnected in series, the positive terminal of each capacitor being connected to the negative terminal of the next. What is the potential difference between the negative terminal of the first capacitor and the positive terminal of the last capacitor? 3. The resistance of a platinum wire at 35.0'C is 20.02. Find the resistance at 45.C. (a=0.0039/Co at 20.0'C) 4. Lightning is a spectacular example of electric current in a natural phenomenon. There is much variability to lightning bolts, but a typical event can transfer 10' J of energy across a potential difference of perhaps 6 x 10' V during a time interval of about 0.3s. Use this information to estimate the total amount of charge transferred, the current, and the average power over the 0.2s.5. A copper wire 3.2mm in diameter carries a 5.0A current. Determine (a) the current density in the wire and (b) the electric field inside the wire. 6. An electric heater draws a steady 20.0A on a 120Vline. How much power does it require and how much does it cost per month (30days) if it operates 3.0h per day and the electric company charges P5.84 per kWh?In this part. all you need to do is to draw the following circuit diagrams. T. Draw a circuit diagram to include a 5W\" battery. an El. Draw a circuit that has a battery. a open switch. 3 ammeter and a resistance of 10.051. resistors and a voltmeter on one resistor connected in parallel. 9. Draw a circuit that has a cell and an open switch 10. Draw a circuit that has an A/C source, an open on the main path, a light bulb on the first branch and switch and two resistors connected in series. a light bulb with an ammeter after it on the second branch connected in parallel
