. Determine the voltage divider supply resistors for the con- figuration in Fig. 7.93. Also determine the required wattage rating for each resistor, and compare their levels. O +120 V 10 mA 20 mA RL A 001 40 mA R2 R3 EA 081 RA 4 mA R5 A 09-O
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.
For the ladder network in Fig. 7.93. Determine the voltage divider supply resistors for the configuration. Also determine the required wattage rating for each resistor, and compare their levels.
