Module 1. Mathematics

Choose the correct statement

• sec^2 * x + tan^2 * x = 1

• cosec^2 * x - cot^2 * x = 1

• cos^2 * x - sin^2 * x = 1

gav_18s asking:

• Can anyone explain this?

Module 3. Electrical fundamentals

If the frequency to a capacitor increases, the current through it

• decreases.

• increases.

• is zero.

obrien99 asking:

• if the formula for capacitive reactance is 1/2piFC

then as frequency increases capacitive reactance would decrease

this would in turn allow more current to flow?

Module 3. Electrical fundamentals

An example of a paramagnetic material is

• silver.

• iron.

• glass.

obrien99 asking:

• Surely this is incorrect too.

iron would fall into the ferromagnet group

silver would fall into the diamagnetic group

glass would fall into the paramagnetic group

Module 3. Electrical fundamentals

The average value of 100 volts peak AC is

• 70.7 volts.

• 141. 4 volts.

• 63.7 volts.

obrien99 asking:

• I think this might be incorrect.

i assume the question is looking for the rms value?

the formula for rms is -

peak voltage x 0.707

or

peak voltage / 1.414

both formulas give 70.7 as the answer

am i missing something?
