Question

the power dissipated in the given circuit through 6 ohm resistance is​

Answer 1

Answer:

The power dissipated in 6 ohm resistor is depends upon the current flow through it. To calculate the current through this resistance first you have to calculate the total resistance offered by this circuit.

First calculate the total resistance-

When R1 and R2 are connected in series then equivalent R would be R1+R2;

And when they are in parallel

R= R1*R2/(R1+R2)

so the total resistance is

So now the total resistance is 15 ohm now calculate the current

V=I*R

V=20V

R=15ohm

I = 20/15= 1.333A

Now you know the same current will flow in 6ohm too so now calculate the power dissipated by 6 ohm resistor.

P=I^2*R

=(1.33)^2 * 6

= 10.6134W
