1. Connect the two-loop circuit as illustrated in Fig. 1, with three variable boxes and two DC supplies. Choose the following values for the resistors and the power supplies: R3 = 700 , R, = 1000.2, R2 = 800 2, ɛj=6 V and ɛ2=12 V. Record these values in Table 1. 2. After the circuit has been checked, close the switches 3. Measure the currents I3,1,1, through resistors and the voltage V3,V1,V½ across each resistor of the circuit. Record these values in Data Table 1. Assuming that only one ammeter will be used, currents through the resistors will be measured one at a time by placing the ammeter in series with the resistor. After the ammeter has been connected, turn on the power supplies and record current.

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.

2.
After the circuit has been checked, close the switches
3. Measure the currents I3,I,1, through resistors and the voltage V3,V, ,V½ across each resistor of the
circuit. Record these values in Data Table 1. Assuming that only one ammeter will be used, currents
through the resistors will be measured one at a time by placing the ammeter in series with the resistor.
After the ammeter has been connected, turn on the power supplies and record current.
