Question

Explain current and circuits with resistors connected in series and in parallel. Also give examples. PLEASE DON'T WRITE IT BY HAND

Answer 1

When resistors connected in series with voltage V then current will be equal through all Resistance . Voltage across them will not which will be. V=IR1 across R1. Similarly others. Current

Which is

I= V/(R1+R2+R3+.......)

Let two Resistance connected in series

R= R1+R2 = 20 ohm

V=10 V

Then I= 10/20

I =0.5 A

When Resistors are connected in parallel with Voltage V

Then potential across resistors will be equal. Current will be different.

I1=V÷R1

I2=V÷R2

........

Total current in parallel circuit

I=I1+I2+.....=V÷R

R=R1×R2..../R1+R2......

For example V=10 V R1=10 ohm R2= 10ohm

I1= V/R1 =10/10 = 1A

I2 =V/R2 =10/10 =1A

Total current using equation ...1

I=1+1 =2

= 10÷(10×10/10+10)

I=2A.
