Answer:
45 ohms
Explanation:
Given
The connection between points A and B is shown in the attachment.
Required
Determine the equivalent resistance
From the attachment, it can be seen that the connection is a connection in series.
The equivalent connection of [tex]R_1,R_2,R_3[/tex] in series is calculated as:
[tex]R = R_1 + R_2 + R_3[/tex]
So, in this case; The solution is:
[tex]R = 20\ ohm + 15\ ohm + 10\ ohm[/tex]
[tex]R = 45\ ohm[/tex]
