What is the voltage of a battery that powers a light with .43 a and has a resistance of 3.5 ohms?

The voltage of the battery is

Explanation:

To answer this question we are going to use the Ohm Law.

Ohm Law is a law that states that the voltage across a resistor is directly proportional to the current flowing through the resistance multiply by the value of the resistance.

Mathematically, we can write :

(I)

Where V is the voltage

Where I is the current

And where R is the resistance

The unit of voltage is V which is volt

The unit of current is ''a'' which is ampere

And the unit of resistance is ohm

If we replace all the data in equation (I) :

The voltage of the battery is

i think the answer is a, hope this : )
