Placement Papers - ACC

First, there was aptitude followed by GD, HR and technical interviews. Aptitude questions for electrical are as follows:

1. 15ohm resistance are connected in parallel then what is the equivalent resistance?
2. What transformer does?
3. If secondary voltage of transformer is 1/4th of primary then secondary current is.
4. Unit of conductance is denoted by (symbol).
5. KVL helps to find out voltages across resistor of the series-parallel circuit. (True or false)
6. If one of the inputs to the gate is zero and it's output is high then which type of gate it is.
7. 15 farads, 3 capacitors are connected in series then equivalent?
8. Out of which is not electrical quantity.
9. 2500 watt means.

I didn't remember options.
