Given the three resistors R1 = 3.13 kW, R2 = 0.52 kW and R3 = 1.59 kW. The potential difference between the points a and b [Figure 1 (a)] is plotted as function of the electric current in the resistor, as shown in Figure 1 (b). 1- For the resistor R3 we used two other multimeters to determine its experimental value. The two multimeters gave the values R3 = 1.36 kW and R3 = 1.61 kW. Determine the four colors of the resistor R3.
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.
