Answer:
Explanation:
Power Dissipated in a resistor is given by two methods i.e.
[tex]P=\frac{V^2}{R}[/tex] and
[tex]P=I^2\cdot R[/tex]
where [tex]V=Potential\ difference[/tex]
[tex]R=resistor[/tex]
[tex]I=current[/tex]
both formula gives Power but Former is used when voltage is constant i.e. when resistors are in parallel and the later is used when the resistor are in series .
Though [tex]P=\frac{V^2}{R}[/tex] can also be used in series but we have to calculate the Potential drop across each resistor then we can apply the formula.
Similar is with [tex]P=I^2R[/tex]
First we have to calculate current through each resistor then we can apply the Formula
