Three parallel connected resistors when connected across a DC voltage source dissipate a total of 72 watts. The total current drawn by the circuit is 6A. If the current flowing on the first resistor is 3A, and the second and third resistors have equal value, What are the resistance of the three resistors?
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.
