The candidates were required to
(i) connect the circuit as shown and take voltage drops at 250Ω and 50Ω resistance values;
(ii) calculate the current flowing through resistors R1 and Rx for the corresponding
voltage drop analogous to fig 1.
The expected answers were
R1(Ώ) |
V1(V) |
Vx(V) |
V1
Vx |
250 |
7.50 |
4.50 |
1.6667 |
50 |
3.00 |
9.00 |
0.3333 |
The candidates understood the task. They connected the circuit and obtained readings but many of the readings and units were wrong.
