A series circuit with a 1 battery (12V), 3 lights, 1 closed switch. A parallel circuit with a 1 cell battery , 2 light bulbs on their own branches, and a voltmeter across(in parallel) the last light bulb. What is the total current? How many volts do each light bulb use? What is the current on each branch? What is the current near the battery? How many volts does each light bulb use?
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.
