Question

Find the value of equivalent resistance across A and B
B​

Answer 1

Explanation:

ANSWER:-

To find Resistance:-

We need to know the 2 types of Resistances

Parallel Resistance

1. This resistance decreases the equivalent resistance
2. Formula is given as

$\frac{1}{x} = \frac{1}{x1} + \frac{1}{x2} + \frac{1}{x3}$

• x is total resistance
• x1 , x2 and x3 are other Resistances
• Reciprocal reduces the resistance
• allows devices to work independently
• preffered for home circuits

Series Resistance

1. This resistance increases the equivalent resistance
2. Formula given as

$x = x1 + x2 + x3$

• x is equivalent resistance
• x1, x2 and x3 are other Resistances
• This does not allow devices t ok work independently.

Questions Reframing :-

Let C and D be the above two resistances.

• Refer C AND D
• From second, we day that C AND D were series,
• So 2+2 gave 4 ohm
• Now parallel , we have

$\frac{1}{x} = \frac{1}{2} + \frac{1}{4}$

$x = \frac{4}{3} \Omega$

d) Part is the answer.
