Hello, two resistors, one with the resistance of 5 and another with the resistance of 9 oms are connected in parallel.
00:20
4 -on resistor, which we label as resistor r2, is connected in series with this parallel combination.
00:33
Let's illustrate it.
00:47
And it's connected to the battery of 6 volts.
00:59
First we have to calculate current through the 9 on resistor.
01:04
We have to calculate current through r2.
01:11
First of all, let's calculate the equivalent resistance.
01:16
The equivalent resistance is r1 or 2 over the sum because it's a parallel connection plus r3.
01:39
Let's calculate it.
01:40
That is 7 .2 oms now let's calculate the equivalent current the total current is emf divided by the equivalent resistance that's 0 .83 amper's and now let's calculate voltage drop across r1 or 2 that is total current times equivalent times the resistance of this part of this rocket...
