Four different resistors have various amounts of electric cu

Four different resistors have various amounts of electric current flowing through them. Given the values of current and resistance in each case, rank the resistors by the voltage across them.

Solution

Apply Ohm\'s law

V = I*R

V ---> potentail difference across resistor

I --> current through the resistor

R --> resiatnce

so, calculate the product of I*R then rank.
