Question

What is the equivalent resistance when three resistors 3ohm,6ohm,and7ohm are connected in series? Draw a circuit diagram

Answer 1

AnsWer :

16 Ohm.

Given :

• we have three Resistance 3 ohm , 7 ohm and 6 ohm.
• All connected in Series Connection.

Concepts Required :

Series Connection

• When any Resistance follow only one path it said to be Series Connection.
• Rs => R1 + R2 + R3.......

Parallel Connection

• When any Resistance change own path two or more in different direction it said to be Parallel Connection.
• 1/Rp => 1/R1 + 1/R2.........

Solution :

All three Resistance connected in Series Combination,

So,

$\bullet \tt R_s = R_1 + R_2 + R_3.....R_n.$

Where as,

• R1 = 3 ohm.
• R2 = 7 ohm.
• R3 = 6 ohm.

$\tt R_s = 3 + 6 + 7. \\ \: \: \: \: \: = \tt 16 \Omega.$

Therefore, the equivalent Resistance of this Circuit is 16 Ohm.
