Common polygons include triangles, squares, rectangles, parallelograms, trapezoids, pentagons, hexagons, octagons… The perimeter of a polygon is the distance around the outside. In general, to find the perimeter of a polygon, you can add up the lengths of all of its sides.

(The induced electric field at the points is so large that it removes the charge from the belt.) This can be done because the charge does not remain inside the conducting sphere but moves to its outside surface.

If we divide both sides of the final equation by V T , we get the relationship between the total resistance of the circuit and the individual parallel resistances in the circuit. The total current through the circuit would be the sum of the three currents in the individual resistors.

(a) Since \(q_{1}\) is positive, the force \(F_{1}\) acting on it is repulsive. (b) The charge \(q_{2}\) is negative and greater in magnitude than \(q_{1}\), and so the force \(F_{2}\) acting on it is attractive and stronger than \(F_{1}\).

It discusses the relationship between resistance (R), current (I), and voltage (V) according to Ohm's Law. Resistance is measured in ohms (Ω), and current can be adjusted by changing potential difference or resistance. Additionally, it includes review questions about Ohm's Law and resistance calculations.
