Question

A resistor of 6 ohm is connected in series with another resistor 4 ohm a potential difference of 20 volts is applied across the combination. Calculate the current in the circuit and potential difference across 6 ohm

Answer 1

Explanation:

First of all add resistances in series:6+4=10ohm

Potential difference applied =20v

Now, V=IR

I=V/R

I=20/10=2Ampere

Now,potential difference across 6 ohm resistor.

V=IR

V=6x2=12V

Answer 2

Answer:

THE current(I)=2A,V across 6 ohm=12V

Explanation:

The two resistors are connected in series

so,the total resistance (R)=6+4=10ohm

By ohms law,

V/R=I

20/10=I

I =2A

The potential diff.across 6ohm

V=IR

V=2×6=12v
