Question

The formula for voltage (in volts) is given by V = IR, where I is the current in amperes, and R is the resistance in ohms. If a light bulb uses 0.4 amperes of current at a voltage of 1.8 volts, the formula to find R is , and the resistance of the bulb is ohms. NextReset

Answer 1

R=V/I for the first one

4.5 for the second one

Explanation:

just took the test on edmentum

Answer 2

the equation for resistance is R=V/A
the answer is 1.8/0.4= 4.5
