Learning Goal: To use the node-voltage method to solve circuits with branches containing only a voltage source. The node-voltage method is a general technique for solving circuits. Fundamentally, it involves writing KCL equations at essential nodes. When the circuit contains a dependent source, you must write a constraint equation for each dependent source, in addition to the KCL equations. When the circuit contains one or more voltage sources that are the only components in branches connecting two essential nodes, the...

PHYC 240-EXAM 3-Practice Problems 3) A 2.00 nF capacitor is charged with a 60.0 V battery. The battery is then removed The charged capacitor is then attached to a 2000.0 ohm resistor at t -o. a) What is the time constant? b) How long until the the charge drops to 20% of its original value? You have an extra 2000.0 ohm resistor. How would you add it to the circuit to reduce the time constant by one half? Draw the...
