find the potential difference when the current is 0.2 amps and the resistance is 30

Question

i just need help finding the andswer to this question could ypu help

Answer 1

Student,

 

You did not state the units of the resistance.  I will assume that it is 30 Ω.  Use Ohm's law.

 

V = IR = (0.2 A)(30 Ω) = 6.0 volts
