1.Two resistances each of 20Ω arranged in parallel are connected in series with 15Ω resistor. What resistance must be shunted across the parallel combination so that the total current taken shall be 3A with 30V supply?
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.
