Question :-
\mapsto↦ If the potential difference across a wire is 2 V & the current passing through the wire is 1 A, the electric power is ________ .
Given :-
\mapsto↦ The potential difference across a wire is 2 V and the current passing through the wire is 1 A.
To Find :-
\mapsto↦ What is the electric power.
Formula Used :-
\clubsuit♣ Electric Power Formula :
\mapsto \sf\boxed{\bold{\pink{P =\: IV}}}↦P=IV
where,
P = Electric Power
I = Current
V = Potential Difference
Solution :
Given :
\bigstar\: \: \bf{Current\: (I) =\: 1 A}★Current(I)=1A
\bigstar\: \: \bf{Potential\: Difference\: (V) =\: 2 V}★PotentialDifference(V)=2V
According to the question by using the formula we get,
\footnotesize\longrightarrow \sf\bold{\purple{Electric\: Power =\: Current \times Potential\: Difference}}⟶ElectricPower=Current×PotentialDifference
\longrightarrow \sf Electric\: Power =\: 1 \times 2⟶ElectricPower=1×2
\longrightarrow \sf\bold{\red{Electric\: Power =\: 2\: Watt}}⟶ElectricPower=2Watt
{\small{\bold{\underline{\therefore\: The\: electric\: power\: is\: 2\: Watt\: .}}}}∴Theelectricpoweris2Watt.
