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

Nirala Anamika Kumari Jaiprakash said: (Jan 28, 2011)  
p=(i*i)r
kvl for ckt
7=5r;
therefore r=7/5;
p=(5*5)*7/5=35;

Sundar said: (May 18, 2011)  
i=v/r
p=i*i*r
r=v/r
r=7/5
r=1.4

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

P=v.i=7.5=35watt

Thanks nirala.

Rajesh said: (Dec 20, 2011)  
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

Viswam said: (Jan 30, 2012)  
P=VI
V=7
I=5
P=7*5 = 35W

Power=Current*Voltage

Ram Ratan Kumar said: (Aug 27, 2012)  
I=V/R
R=V/I
R=7/5=1.4
P=I*I*R
P=5*5*(1.4)
=35W

Parul Singh said: (Sep 20, 2012)  
P=VI
V=7
I=5
P=7*5 = 35W

Elizabeth said: (May 21, 2014)  
P = VI.

I = 5.
V = 7.

P = 7*5.
= 35.

Pravalika said: (Jun 28, 2016)  
Power = current * voltage.

Madhu said: (Dec 11, 2016)  
Power P =vi = voltage * current = 5 * 7 = 35.

Madhan said: (Jan 25, 2017)  
Here, Power = v * i.

Baskar said: (Mar 15, 2017)  
P = vi.
P=7 * 5 = 35.

Gautam said: (May 4, 2017)  
Formula, P = V * I.

= 7 * 5 = 35 W.

Solomon said: (Jan 19, 2018)  
P=v*I . P=7*5 therefore power is 35 w.

Raiyan Khan said: (Jul 18, 2018)  
Here, power=I*V.

Manojit said: (Oct 27, 2018)  
We know, P = V.I.
P=(5*7)watt.
P = 35 watt.
