Question

A battery of 6v is connected in series with resistors of 1ohm, 2ohm and 3ohm. How much current will flow through 2ohm resistor? ​

Answer 1

Given

✭ Potential difference = 6V

✭ Three resistors of 1Ω,2Ω & 3Ω are connected in series

To Find

◈ Current through the 2Ω resistor?

Solution

Concept

So here we shall use the Ohm's law to find the current through the resistor.We are given that there are 3 resistors in the circuit get we are only asked about the 2Ω resistor so we can simply avoid the other two

━━━━━━━━━━━

Ohm's law is that,

V = IR

◕ V = Voltage

◕ I = Current

◕ R = Resistance

Substituting the given values,

➝ V = IR

➝ 6 = I × 2

➝ 6/2 = I

➝ I = 3 A

∴ Current through the 2Ω resistor is 3A
