P=VI , P=I2R, P=V2/R

p=(i*i)r
kvl for ckt
7=5r;
therefore r=7/5;
p=(5*5)*7/5=35;

Sundar said:   1 decade ago
i=v/r
p=i*i*r
r=v/r
r=7/5
r=1.4

p=1.4*(5 * 5)
p=35

Thanks nirala.

Rajesh said:   1 decade ago
power=(I*I)R

We know that R=V/I
=7/5=1.4 ohm
p=(5*5)1.4=35w

V=IR
=>R=V/I
=>R=7/5
=>R=1.4
P=I*I*R
=>P=5*5*1.4
=>P=35w

P=VI
V=7
I=5
P=7*5 = 35W

Power=Current*Voltage

Ram Ratan Kumar said:   1 decade ago
I=V/R
R=V/I
R=7/5=1.4
P=I*I*R
P=5*5*(1.4)
=35W
