Question

In a lab activity Harsha connected 3Ω,5Ω, 7Ω resisters in series . Then what will the final resistance he

could get?​

Answer 1

Answer:

R=r1+r2+r3

R=3+5+7

R=15volts

Answer 2

Gɪᴠᴇɴ :-

• Resistors = 3Ω,5Ω, 7Ω
• Way of connection = In series

ᴛᴏ ғɪɴᴅ :-

• Final Resistance

sᴏʟᴜᴛɪᴏɴ :-

We know that,

Series Combination of resistors :-

In series combination the equivalent resistance is the sum of the individual resistances.For more resistor,the above expression would have been,

➦ Resistance in Series = Resistance 1 + Resistance2,+.......n

➦ Rn = R1 + R2 +,.....n

On putting above given values in it, we get,

➦ R = 3Ω + 5Ω + 7Ω

➦ R = 15Ω

Hence,

• Final Resistance = 15Ω
