Question

Calculate the potential difference across 15 ohm resistor

Answer 1

Therefore, potential difference across 15ohm resistor is 1Volt.

:)

Answer 2

Concept Introduction: Resistance calculation is the basic part of physics numericals.

Given:

We have been Given: The following diagram with three resistors in series are

$5 \: ohm \\ 10 \: ohm \\ 15 \: ohm$

connected to a source of potential

$2v$

To Find:

We have to Find: Calculate the potential difference across 15 ohm resistor.

Solution:

According to the problem, Equivalent Resistance is

$r(series) = 5 + 10 + 15 = 30 \: ohm$

therefore current flowing through it is

$v = ir(eq) \\ 2 = i \times 30 \\ i = \frac{1}{15} a$

therefore the potential difference across the 15 ohm resistor is

$v = ir1 \\ = \frac{1}{15} \times 15 \\ = 1 \:v$

Final Answer: the potential difference across the 15 ohm resistor is

$1 \: v$
