Hi, in this question we have three resistors, r1, r2 and r3 in this circuit, which is connected through a voltage of 12 volts.
00:10
So we have to calculate in the first part we have to calculate the total current in this circuit.
00:18
So now through oms clock we know that the current i can be calculated using the formula i equals to v by r where v is the voltage and and r is the total resistance of the circuit.
00:35
So, i can be calculated as 12 hold divided by, so total resistance of this circuit, since these resistance are in series, so we'll have the total resistance as sum of r1, r2 and r3.
00:51
So this will be equals to 6 plus 8 plus 10.
00:55
Hence we'll get the value of i as 12 divided by 24.
00:59
Or we can say that the total current i that will be flowing in this circuit is equals to 0 .5 ampere.

So now in the second part, they're asking us to calculate the voltage across r1...
