Imagine a single-loop circuit with a battery, and three resistors R1, R2, R3 connected in series. Resistance is ignorable except for the resistors. Resistors are ohmic. Answer the following question. a. (0.5) Which (if any) physical quantity- among resistance R, current I, and voltage V must be the same for the three resistors?
b. (0.5) How are R, I, and V related for each resistor in this circuit? Answer with an equation involving these three quantities.

State the right hand rule of the direction of magnetic field in a conductor carrying current

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
