- Two parallel plates with an area of 3.0 cm2 are separated by a 2.5 mm thick dielectric with a constant of 4.70. If the potential difference between the plates is 120 V and the conduction current ic is 6.00 mA a) what is the charge (q) on each plate?1) so that the current varies by less than 10% as the load resistance (R) changes from 200 to 500N. The current must be at least 1.5 mA. For V = 10 Volts, find a resistance R which will meet these criteria. You want to make a current source from a battery (V) and resistor (R) R I V- RLIn a certain region of space, the current density is ] = C(x³î + y³ĵ + z³k), being the value of the constant "C" equal to 10-3, the coordinates x, y and z are in meters. I) II) III) Find the units of the constant C. How fast does the charge density "p" (in C/m³.s) change at the point P with coordinates equal to (2, -1, 4) m? Find the rate of change of the electric charge contained in a sphere of radius R=20 cm with center at the origin 0, for a given instant of time.
