Question

three resistor of 4ohm,6ohm and 10ohm are connected in series. What is their equivalent resistance.​

Answer 1

Answer:

Explanation:

According to ohm’a law

V=IR

R= r1+r2+r3

R=4+6+10

R=20 ohm

Total resistance in series connection= 20 ohm

V=IR

I=V/R

I=5/20

I=0.25 A

In series connection, current through each resistor is same

Let V1,V2 and V3 be the potential differences across resistors r1 ,r2 and r3 respectively

V1= I*r1=0.25*4= 1 volt

V2 = I* r2=0.25*6=1.5 volt

V3= I/r3=0.25*10=2.5 volt

Answer 2

Answer:

20 Ohm

Explanation:

In a series circuit, to calculate the resistance, you need to add all the three values.

4+6+10 = 20 Ohm.
