Now this question is the circuit that we are given.
00:04
The first part we want to find the equivalent resistance of the entire circuit.
00:10
So r equivalent, since they are all in series to each other, we just add all the resistance up.
00:17
So just r1 plus r2 plus r3 should get 9 oms.
00:26
Next to find the current through each resistor, since they are in series again, they are current is shed, so they have the same current from the total equivalent resistance.
00:40
So i.
00:40
It goes to v over r.
00:44
The voltage is the total voltage divided by the total resistance.
00:53
It gives us 2 ampiers.
00:59
Next, the potential drop across each resistor...
