23. Use the circuit belоw tо find the fоllowing: (You must show work аnd re-drаw the circuit аs you simplify to find equivalent resistance. ) (12 pts) a) The total circuit resistance ( be sure to show each of the circuits as you simplify) b) The current leaving the battery c) the voltage across the 40 ohm resistor d) the current through the 30 ohm resistor. 24. Redraw the circuit below showing how an ammeter would be connected to measure the total current and how a voltmeter would be connected to measure the voltage across R3. (4 pts.) 25. A 2.00 and a 7.50 uF capacitors can be connected in series or parallel, and a 25.0 and 100.0 kilo ohm resistors can also be connected in series or parallel. The different combinations can create 4 different circuits. Calculate the four RC time constants possible from connecting the resulting capacitance and resistance in series and parallel combinations. (ie. both series, series and parallel and both parallel) (8 pts) 26. Draw a bar magnet and identify the north and south poles. Draw the magnetic fields lines created by the magnetic field of the magnet.(4 pts) 27. Two long straight wires are each carrying 3.00 A of current, as shown in the diagram. The spacing between each wire and the wire closest to point P is the same at 0.500 m. (10 pts) a) Find the magnitude and direction of the magnetic field at point P for each of the wires? b) What is the overall magnitude and direction of the magnetic field at point P? 28. In the figure below, an edge-on view of a 10.00 cm diameter circular loop is rotating in a uniform 0.050 T magnetic field. (8pts) a) What is the magnetic flux through the loop when theta is 0, 30, 60 and 90 degrees? b) Which of the above would create the largest induced current? 29. The lowest frequency in the FM radio band is 88.0 MHz. Assuming the radio is in a car with a 12-volt battery and a 2.50 pF capacitor, calculate the following: (10 pts) a) the inductance needed to produce this resonant frequency? b) At resonance, what is the peak current through this circuit?
