Three resistors R1, R2 and R3 are connected in parallel. This parallel circuit is connected in series to a fourth resistor 'R'. The entire circuit is supplied by a 25 volts DC source. If the values of R1= 13ohm, R2= 12 ohm R3= 10 ohm and the power dissipated from R3 is 18 watt find the value of resistor 'R'
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.
