Question

in an electric circuit resistance is 55 ohm and current 4 ampere. what is voltage?

Answer 1

here
V=IR
V=4*55
V=220ohm

Answer 2

ohm's law states that at constant temperature
the current and voltage are directly proportional

by ohm's law
V=IR
(V is voltage, I is current and R is resistance)
given data in question
I=4A
R=55ohm

thus V=IR=4*55=220V
so ur ans is 220 volt
