Question

Select all that apply.

Which factors determine the amount of electric current in a circuit?
switch
ammeter
voltage
resistance

Answer 1

So, voltage (U) and resistance (R) are linked with current (I) by the equation
`I = (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.

Answer 2

In order to help the student expand his/her 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

I hope it helps, Regards.
