3. The capacitors in the circuit shown below are charged and the switch closes at t = 0 s. 6Ω #100 µF 50 μF 40 Ω: 60 Ω (AVJ, = 9 V #100µF (a) tance, and the time constant of this circuit. Determine the total (equivalent) capacitance, total (equivalent) resis-
KVL and KCL
KVL stands for Kirchhoff voltage law. KVL states that the total voltage drops around the loop in any closed electric circuit is equal to the sum of total voltage drop in the same closed loop.
Sign Convention
Science and technology incorporate some ideas and techniques of their own to understand a system skilfully and easily. These techniques are called conventions. For example: Sign conventions of mirrors are used to understand the phenomenon of reflection and refraction in an easier way.
d. Determine the current through and potential across each resistor when the current is at 50% of its initial value.
