Question

If the resistance of resisters are 2 ohm and 3 ohm find the effective resistance in series and parallel

Answer 1

Answer:

series connection

2+3=5ohm is net resistance of series connection

parallel connection

2+3÷

3×2 that is 5/6 ohm

Answer 2

Answer:

Series = 5 ohms

Parallel = 1.2 ohms

Explanation:

Given :

• Resistance of the first resistor = 2 ohms

• Resistance of the second resistor = 3 ohms

To find :

• Effective resistance when the resistors are connected in series

• Effective resistance when the resistors are connected in parallel

When resistors are connected in series, effective resistance = R1+R2+R3......

When resistors are connected in parallel, 1/effective resistance = 1/R1+1/R2...

Series combination :

=2+3

=5 ohms

Parallel combination :

1/effective resistance = 1/2 + 1/3

1/effective resistance = 3/6 + 2/6

1/effective resistance = 5/6

Effective resistance = 6/5 = 1.2 ohms

The effective resistance in series combination is 5 ohms and parallel combination is equal to 1.2 ohms
