Question

Explain current and circuits with resistors connected in series and in parallel. Also give examples. (Please NOT by hand)

Answer #1

current is i

the resultant resistance is R

when **resistors** are conncted in
**series**

**R = R _{1} + R_{2} +
........**

here using Ohm's Law we can write V = i R

i_{series} = V / R

**i _{series} = V / R_{1} + R_{2} +
........**

and sameway

when **resistors** are conncted in
**parallel**

**1 / R = 1/R _{1} + 1/R_{2} +
........**

here using Ohm's Law we can write V = i R

i = V / R

**i _{parallel} = V X (1/R_{1} +
1/R_{2} + ........)**

finally we can conclude that,

**when the resistors are connected in series the
resistance is High and current is Low,**

and

**when the resistors are connected in parallel the
resistance is Low and current is High.**

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.

Resistor R1=3.7 Ohm is connected in series to parallel combination
of resistors R2=7.9 Ohm and R3=11.1 Ohm. Find equivalent resistance
of this combination. Give answer in Ohms.
Resistor R1=3.7 Ohm is connected in series to parallel combination
of resistors R2=7.9 Ohm and R3=10.7 Ohm. This combination is
connected to the ideal battery of V=10.6 V. Find current through
the R3. Give answer in A.

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?

Two 8.1 ? resistors are connected in parallel, as are two 4.7 ?
resistors. These two combinations are then connected in series in a
circuit with a 14 V battery.What is the current in each resistor
and What is the voltage across each resistor

1.Two 60.0 Ω resistors are connected in parallel and
this parallel arrangement is then connected in
series with a 30.0 Ω resistor. The combination is placed across a
120V potential difference. Can you
design the circuit diagram using above data? According to your
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
