Question

write circuit diagram for registors in series and resistors in parallel

Answer 1

Answer:

Explanation:

The diagram of three resistors connected in series combination is shown.

R  

1

​  

,R  

2

​  

 and R  

3

​  

 are the three resistors.

I = electric current flowing through the circuit

V = the potential difference supplied by the battery

Applying the Ohm’s law to the entire circuit, we have

V=IR

On applying Ohm’s law to the three resistors separately, we further have

V  

1

​  

=IR  

1

​  

 

V  

2

​  

=IR  

2

​  

 

and V  

3

​  

=IR  

3

​  

 

The total potential difference across a combination of resistors in series is equal to the sum of potential difference across the individual resistors. That is,

V=V  

1

​  

+V  

2

​  

+V

​  

 

Therefore, IR=IR

​  

+IR

​  

 

or

Equivalent resistance of the combination, R=R
