00:00:00,090 --> 00:00:03,900
worked example of a series circuit from the series circuit

2
00:00:03,900 --> 00:00:07,980
shown in the figure calculate the total equivalent resistance of

3
00:00:07,980 --> 00:00:12,270
the circuit the total current flowing through the circuit the

4
00:00:12,270 --> 00:00:16,470
current flowing through each resistor the voltage or potential difference

5
00:00:16,470 --> 00:00:20,040
across each resistor the power supplied by the cell

6
00:00:20,193 --> 00:00:24,240
the power dissipated in the circuit the total equivalent resistance

7
00:00:24,240 --> 00:00:27,390
of the circuit we obtain the total resistance of the

8
00:00:27,390 --> 00:00:30,720
circuit by grouping all the resistors in series together which

9
00:00:30,720 --> 00:00:33,810
is the same as adding them all up b the

10
00:00:33,810 --> 00:00:37,620
total current flowing through the circuit the second figure shows

11
00:00:37,620 --> 00:00:40,320
the resulting equivalent circuit to cal

12
00:00:40,350 --> 00:00:43,320
collate the total equivalent current we need to apply ohm's

13
00:00:43,320 --> 00:00:47,190
law to the equivalent circuit the voltage or potential difference

14
00:00:47,190 --> 00:00:51,450
across each resistor to calculate the voltage or potential difference

15
00:00:51,450 --> 00:00:54,690
across each resistor we apply one's law using the values

16
00:00:54,690 --> 00:00:58,020
that we have already calculated we can check that we

17
00:00:58,020 --> 00:01:00,480
have done the exercise correctly by adding up the protests

18
00:01:00,480 --> 00:01:03,960
central differences across each resistor the result must be equal

19
00:01:03,960 --> 00:01:07,500
to the voltage delivered by the cell the power supplied

20
00:01:07,500 --> 00:01:09,900
by the cell and the power dissipated in the circuit

21
00:01:10,740 --> 00:01:13,380
the dissipated power is the sum of the power consumed

22
00:01:13,380 --> 00:01:17,130
by each resistor the power delivered by the cell is

23
00:01:17,190 --> 00:01:19,890
the voltage of the cell by the total intensity of

24
00:01:19,890 --> 00:01:20,550
the circuit

25
00:01:21,360 --> 00:01:24,660
we confirmed that the delivered power and the participated in

26
00:01:24,660 --> 00:01:25,890
the circus are equal
