A coil of resistance 16 ohm is connected in parallel with a coil of resistance R₁. This combination is then connected in series with resistances R2 and R3. The whole circuit is then connected to 220 V D.C. supply. What must be the value of R1 so that R₂ and R3 shall dissipate 800 W and 600 W respectively, with 10 A passing through them?
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.
