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.

Series/Parallel Circuits: When unequal resistors are connected
in series across an ideal battery,
the same power is dissipated in each one.
the potential difference across each is the same.
the equivalent resistance of the circuit is equal to the
average of all the resistances.
the current flowing in each is the same.
the equivalent resistance of the circuit is less than that of
the smallest resistor.

In a circuit, a parallel combination of six 2.6 kΩ resistors is
connected in series with a parallel combination of four 3.0 kΩ
resistors. The source voltage is 24 V.
If this circuit is modified by removing some of the 2.6 kΩ
resistors, the total current in the circuit is 18.9 mA. How many
resistors were removed?

observation show that total voltage is
equal to the sum of the individual voltage and also show that total
power dissipated is equal to the sum
of the power dissipated by individual resistor. Also suggest what
