Estimate the electric fields at points 1 and 2 in Figure Q26.5. Don’t forget that is a vector.
What is the potential difference in Figure EX26.16?
Find expressions for the equivalent capacitance of
(a) identical capacitors in parallel and
(b) identical capacitors in series.
The label rubbed off one of the capacitors you are using to build a circuit. To find out its capacitance, you place it in series with a capacitor and connect them to a battery. Using your voltmeter, you measure across the unknown capacitor. What is the unknown capacitor's capacitance?
The electric potential in a region of space is V=200/2x2+y2,where x and y are in meters. What are the strength and direction of the electric field at 1x, y2=12.0 m, 1.0 m2? Give the direction as an angle cw or ccw (specify which) from the positive x-axis
