Question

50. What is the resistance between A and B in the figure given below ?​

Answer 1

Answer:

Resistance = 10 + 1/(1/30+1/50)+10

= 20+ (1500/80)

= 20 +75

=95 Ohms

Step-by-step explanation:

Answer 2

Answer:

38.75 ohms.

Step-by-step explanation:

The three resistance of 20 ohm, and 10 ohm and 20 ohm on the extreme right side are in series.

So, the resultant of these three resistances = 20+20+10 = 50 ohms

This 50 ohms is in parallel with 30 ohms.

This 50 ohms is in parallel with 30 ohms. So resultant of these two will be

1/R = 1/30 +1/50 1/R = 80/1500

R = 18.75 ohms Now, the resistances 10 ohms, 18.75 ohms and 10 ohms are in series.

Therefore, resultat resistance = 18.75 + 10+ 10 = 38.75 ohms.
