Question

When a circuit is set up correctly, it is found that a voltage of 3 V gives a current of 0.5 A. What voltage would be needed to give a current of 1 A?

Answer 1

Given that -:

• Voltage , Potential difference (v) = 3v
• Current (I) = 0.5 A

To find -:

V( voltage) = ? when Current (I) = 1 A .

Let,s find-:

------> 3 v = 0.5 A

------> V = 0.5 / 3

------> V = 1/6 v or ( 0.166 v )

Therefore, 1V = 0.166 v

Hence , 0.166 volt of voltage would be needed to give a current of 1 A
