All right.
00:02
To solve this question or this problem first let's draw the circuit diagram.
00:08
Here we have a battery.
00:10
This is positive.
00:11
This is negative.
00:11
This is negative terminal.
00:12
With this battery we have a register connected.
00:15
With this resistor we have another register connected this way and this branch is connected to the negative terminal of the battery.
00:23
In parallel with this register, we have another register connected this way and this is connected here.
00:29
Now let's label the circuit diagram.
00:34
This voltage source, it is of 24 volts.
00:42
This resistor, let's call it r1, it is of 20 oombs.
00:51
Let's call this resistor r2, it is of 5 oom, and let's call this resistor r3, it is of 10 oom.
01:04
And let's say the current through this resistor let's level it i1 and let's say the current through this resistor let's label it i2 and let's label the current flowing through this resistor as simple i all right now first of all we will find the equivalent resistance or the parallel combination of these two registers the parallel combination of these two resistors is given by their product there is 5 times 10 divided by their sum 5 plus 10 5 multiply by 10 is 50 divided by 5 plus 10 is 15 50 divided by 15 will give us 3 .33 oh so this is the pedal combination of these two registers now let's say the voltage across this resistor is given by v1 and let's say the voltage across this resistor is given by v2 they both are in parallel it means their voltage should be equal in parallel combination the voltage is equal so it is equal to it means this 24 volt will be divided between this resistor and these registers so we will use the formula of potential divider that is total voltage 24 volts time this their parallel combination there is 3 .3 oom divided by the sum of the resistances.

This whole gives us 3 .3 oom and this is 20 oom...
