Electricity can be a hazard in hospitals, particularly topatients who are connected to electrodes, such as an ECG.Suppose that the motor of a motorized bed shorts out to thebed frame, and the bed frame's connection to a ground hasbroken (or was not there in the first place). If a nurse touchesthe bed and the patient at the same time, the nurse becomesa conductor and a complete circuit can be made through thepatient to ground through the ECG apparatus. This is shownschematically in Fig. 19–75. Calculate the current through thepatient.Bedww(low R)Patientwo104 2Nurse104 2ECG- apparatus(low R)1042|Motor240 VFIGURE 19–75 Problem 70.

Dear sir Hand written solution is not allowed.
THE POLARITY MARKINGS ON TWO WINDINGS MUST BE DETERMINED EXPERIMENTALLY. THE DEVICE FOR SUCH DETERMINATION IS SHOWN IN THE FIGURE BELOW. THAT THE TERMINAL CONNECTED TO THE POSITIVE TERMINAL OF THE BATTERY RESERVES THE POLARITY MARKING AS SHOWN IN THE FIGURE. WHEN THE SWITCH IS OPEN, THE DC VOLTMETER UNDERGOES A NEGATIVE DEFLECTION. WHERE ON THE CONNECTED WINDING SHOULD A POLARITY MARKING BE ATTACHED TO THE VOLTMETER? t = 0 R )cc VOLTIMETER VB- CHOOSE AN OPTION BELOW: A. POINT AT THE LOWER END OF THE INDUCTOR B. POINT AT THE TOP END OF THE INDUCTOR C. NONE OF THE OPTIONS D. A DOT AT THE TOP END AND BOTTOM END C E. THERE IS NO COUPLING BETWEEN THE INDUCTORS, SO IT IS NOT NECESSARY TO PLACE A DOT
In the figure below, the rolling axle, 2.90 m long, is pushed along horizontal rails at a constant speed v = 12.00 m/s. A resistor R = 0.4000 N is connected to the rails at points a and b, directly opposite each other. The wheels make good electrical contact with the rails, so the axle, rails, and R form a closed-loop circuit. The only significant resistance in the circuit is R. A uniform magnetic field B = 0.0300 T is vertically downward. B b. (a) Find the induced current I in the resistor. A (b) What horizontal force F is required to keep the axle rolling at constant speed? N (c) Which end of the resistor, a or b, is at the higher electric potential? O Point a is at a higher potential. Point b is at a higher potential. O Point a and point b are at equal potentials. (d) After the axle rolls past the resistor, does the current in R reverse direction? O Yes No

1) A superconducting magnet carries a 100A current through a 0.5mm diameter superconducting wir that is wound into a coil. a) what is the current density? b) how much charge flows through the wire in 15min?
We will often use water as an analogy for electricity. This can help us to visualize circuits and current flow. However, this analogy doesn't always work. After learning about the laws attraction and magnetic induction, what are some ways that you can think of that demonstrate how the flow of electrical current is different than the flow of water?
Which statement is true about a resistor? O A resistor stores energy in an electric field and returns that energy to the circuit. O A resistor stores energy in a magnetic field and returns that enrgy to the circuit. O A resistor absorbs heat and and dissipates electrical energy O A resistor absorbs electric power and dissipates heat
