Question
To have a 10 V potential difference, we need___ .
To have a 10 V potential difference, we need
Open in App
Solution
The correct option is A 0.5 ohm resistor and 20 A current
By Ohm's law, we know that,
V = IR
By going through all the options, we get a product of I and R as 10 when we have R = 0.5 ohm and I = 20 A.
