A current of 2 ampere is flowing through a wire of resistance 24 ohm. What is the potential difference across the conductor
Answers
Answer:
Correct option is
B
75Ω
Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance, we arrive at the usual mathematical equation that describes this relationship: I=
R
V
,
where, I is the current through the conductor in units of amperes, V is the potential difference measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms.
Therefore, R=V/I.
R=
0.2
15
=75Ω
Explanation:
plz bro make me brain list
Given :-
Current = 2 Ampere
Resistance = 24 ohm
To Find :-
Potential difference
Solution :-
In order to solve, we have to first know the formula
V = IR
Where
V stands for potential difference
I stands for Current
R stands for resistance
V = 2 × 24
V = 48 Volt
