Three resistors R1,R2, and R3, are connected in series and to a 120-volt source. If R2 = 2R1, R3 = 3R1, and the total power taken by the circuit is 200 watts, calculate (a) the resistance of each resistor, ( b) the power in each resistor
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.
