So, voltage (U) and resistance (R) are linked with current (I) by the equation \(I = \frac{U}{R}\), that THE basic law of electricity. Onther two things mentioned are a component (switch), a mechanical part, and an instrument (ammeter), that is used to measure the current, but does not change or control it. The answer is Voltage and Resistance.

knowledge I will help answer the question. This in hope that the student will
get a piece of knowledge that will help him/her through his/her homework or
future tests.


All of the mentioned factors determine the
amount of electric current in a circuit exept for the ammeter. The ammeter is a
measuring tool which does not affect the lfow of electric current in a circuit.
The answer is



Switch

Voltage

Resistance
