Question

question 3 of 15
what is true about current?
check all that apply.
a. it is measured in ohms.
b. it is measured in amps.
c. it is the flow of electric charges.
d. it is related to voltage and resistance by ohms law.
e. it is the excess accumulation of electric charge.

Explanation:

• Option A: Ohms are the unit of resistance, not current. So this option is incorrect.
• Option B: Current is measured in amperes (amps). This is correct.
• Option C: Electric current is defined as the flow of electric charges (usually electrons in a conductor). This is correct.
• Option D: Ohm's Law \(I=\frac{V}{R}\) (where \(I\) is current, \(V\) is voltage, and \(R\) is resistance) shows the relationship between current, voltage, and resistance. This is correct.
• Option E: The excess accumulation of electric charge is called static electricity, not current. So this option is incorrect.

Answer:

B. It is measured in amps.
C. It is the flow of electric charges.
D. It is related to voltage and resistance by Ohm's Law.
