A parallel circuit contains four resistors. The total resistance of the circuit is 120 ohm. Three of the resistors have values of 820 ohm, 750 ohm, and 470 ohm. What is the value of the fourth 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.
