Hi, here we have to calculate power delivered to each resistor.
00:03
Let's do this.
00:04
So first let's, we have to calculate it for the resistor 1.
00:09
Let's do this.
00:12
So let's make the sketch and let's label resistance of 1 ohms as r3 and the resistance of 4 ohms as r4.
00:38
So now let's calculate the equivalent resistance.
00:45
Now let's calculate it.
01:14
So it's 7 .67 ohms.
01:16
Now let's calculate total current through the battery.
01:31
So that's 1 .57 amperes.
01:34
And now we can calculate power delivered through the resistance r1.
01:40
That is i total squared times r1.
01:53
That's 7 .35 watts.
01:57
Okay, now we have to focus on the 4 ohm resistor and here that is labeled as r4.
02:12
So here current through r4 equals to the current through r1...
