PHY 215 Study Guide - Final Guide: Kirchhoff'S Circuit Laws
Document Summary
The sum of the potential differences across all elements around any circuit loop must be zero. If a capacitor is charged with a battery through a resistor of resistance r, the charge on the capacitor varies in time according to q(t) = If a capacitor is charged with a battery through a resistor of resistance r, the current in the circuit vary in time according to i(t) = If a charged capacitor is discharged through a resistor of resistance r, the charge decreases exponentially as q(t) = If a charged capacitor is discharged through a resistor of resistance r, the current decreases exponentially as i(t) = The magnetic force that acts on a charge q moving with a velocity v in a magnetic field b is f = q*(v x b) The magnitude of the magnetic force is f = qvb*sin and it is in a direction perpendicular both to the particle and the magnetic field.
