Assume that you have a configuration of conductors with varying electric potentials applied to each, such as you will be dealing with in this lab. you make the following measurements of the values of the electric potential at different points in a dimensional grid: x = 0.00 cm y = 0.0 cm v = 2.0 volts x = 0.00 cm y = 0.00 cm v = 2.25 volts x = 0.00 cm y = 0.00 cm v = 2.0 volts what are the values of the x and y components of the electric field at the origin (e_x and e_y at (x, y) = (0, express the results in si units. for on doing this problem, read question 1 -6 in this lab writeup.

The eel has a certain amount of rotational kinetic energy when spinning at 14 spins per second. if it swam in a straight line instead, about how fast would the eel have to swim to have the same amount of kinetic energy as when it is spinning?

For problems 1-3, consider a simple dc brush motor with a permanent magnet stator. with an an consider a simple dc brush motor with a permanent magnet ae supply voltage of 100 v, the no-load speed of the motor is 1000 rpm. this motor can provide a torque of 1.9 n-m at 800 rpm drawing a current of 2 a current are both zero at no load.) 1. with an armature supply voltage of 100 v, the motor is operated at 900 rpm. what is the motor torque? what is the mechanical power delivered by the motor? what is the current draw? what is the electrical power input? what is the energy efficiency of the motor? with an armature supply voltage of 100 v, the motor is operated at 1100 rpm (where it acts as a generator). what torque input is required? what mechanical power is required what current is generated? what is the electrical power generated? what is the energy efficiency of the motor acting as a generator? 2. with an armature supply voltage raised to 120 v, the motor is operated at 1000 rpm. what is the no-load speed? what is the motor torque? what is the mechanical power delivered by the motor? what is the current draw? what is the electrical power input what is the energy efficiency of the motor? 3.
