Select all of the following statements which are true regarding Kirchhoff’s Current Law (KCL). Select one or more: The algebraic sum of all voltage drops around a loop must be zero The algebraic sum of all voltage rises around a loop must be zero The algebraic sum of all currents entering a loop must be zero The algebraic sum of all currents exiting a loop must be zero The algebraic sum of all voltage drops exiting a node must be zero The algebraic sum of all voltage rises exiting a node must be zero The algebraic sum of
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.
