Answer 2

Given:

R1 = 10Ω

R2 = 20Ω

V = 3v

To find:

Potential difference across 10Ω resistor.

Solution:

1) The given resistors are in the series so the resultant resistance will be     R1 + R2 = 30Ω.

2) According to the ohms law we have,

• V = IR

• 3 = I. 30

• I = 0.1 A

3) As we know that in the series arrangement the current flowing to the resistors will be same at every point.

4) So again by the ohms law the potential difference across 10Ω

• V = IR

• V = 0.1 × 10

• V = 1v

Potential difference across 10Ω resistor = 1 V.
