Question

Calculate the potential difference across a 25- resistor if a 0.3-A current is flowing through it. V

Answer 1

By Ohm's law

V = IR


we have
R (resistance) = 25 Ω 
electic current (I)= 0.3 A


substitute these values in V = IR and you'll get

V (potential difference ) = 25 × 0.3 V = 7.5V

Answer 2

Answer:

7.5 V
