The candidates were required to:
(i) connect the circuit as shown and obtain voltage readings;
(ii) compare the voltage sum across the load with the source voltage;
(in) state the law that governs the result obtained in the Experiment 2.
The expected answers were:
Table 2
Vs(V) |
V1 (V) |
V2 (V) |
V3 (V) |
V1+ V2 + V3 (V)
|
12.0 |
0.112 |
1.085 |
10.806 |
12.003 |
(g) V1+ V2 + V3 = 12.00 V
(h) On comparing the result obtained in (g) with Vs , the two are the same or V1 +V2+ V3 = Vs .
(i) The law that governs the result obtained in the experiment is Kirchhoff'sVoltage Law which states that the voltage applied to a close circuit equals the sum of the voltage drops in that circuit.
The candidates undertook the task that was the opposite of that which
they did in Experiment 1 by connecting the loads in parallel. However,
most of the readings were not correct due to their inability to read
correctly the measuring instruments, which took a toll on the table
obtained for the experiment.
