B. Voltage
C.Direct current
D.resitance

anonymous · Answer

what is resitance?

anonymous · Answer

I'm doing a problem from electricity and electronics

anonymous · Answer

You can give more than one answer?

anonymous · Answer

no its multiple choice as shown above

anonymous · Answer

If the voltage remain the same I would say resistance, that's follows from Ohm's law:
$$I=\frac{ V }{ R }$$

anonymous · Answer

The more is R, the less is I

anonymous · Answer

can you please help me with one more question

anonymous · Answer

Yes of course :)

anonymous · Answer

A transformer has a primary voltage of 115 V and a secondary voltage of 24 V. If the number of turns in the primary is 345, how many turns are in the secondary?

anonymous · Answer

A. 690
B. 72
C. 8
D. 1,653

anonymous · Answer

Ok, you must use :
$$\frac{ T _{1} }{ T_2 }=\frac{ V_1 }{ V_2 }$$
So: 72

anonymous · Answer

thank you so much

anonymous · Answer

T_1 is turn one and T_2 is turn 2 of course ;)
