In the Coulomb's Law experiment, the spheres were charged by touching with a voltmeter ground probe charging probe ammeter The charges carried by the spheres above were proportional to the potential current resistance temperature By mapping the equipotential lines, you can draw the charge the electric field lines nothing the magnetic field lines In which of the following experiments a galvanometer was NOT used? mapping of the electric field study of a source of emf and terminal voltage the Wheatstone...
8. Capacitance in circuits, RC circuits When a voltage source Vo is applied to a capacitor in a circuit which has a resistance R, a charge Q CV will build up across the capacitor. This does not happen instantaneously, but takes some time. The charge builds up exponentially with a characteristic time r = RC. Charging: V = v. 1 - e-t/RC) Discharging: Vc = V e-t/RC Page 2 of 3 When t = RC , the exponential is lle,...
