We know that, P=V.I.
So, here V= 7 Volts,I = 5A,
then, P=7/5=35Watts.
The units for power is watts.
So, here V= 7 Volts,I = 5A,
then, P=7/5=35Watts.
The units for power is watts.

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

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

i=v/r
p=i*i*r
r=v/r
r=7/5
r=1.4
p=1.4*(5 * 5)
p=35
p=i*i*r
r=v/r
r=7/5
r=1.4
p=1.4*(5 * 5)
p=35

Power P =vi = voltage * current = 5 * 7 = 35.

We know, P = V.I.
P=(5*7)watt.
P = 35 watt.
P=(5*7)watt.
P = 35 watt.

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

P=v*I . P=7*5 therefore power is 35 w.
