Question

what electrical property is sams when resistors are joined
1• in series.
2• in parallel
in a circuit ..

please ans this♥️♥️♥️

Answer 1

A Parallel circuit has certain characteristics and basic rules:

1.A parallel circuit has two or more paths for current to flow through.
2.Voltage is the same across each component of the parallel circuit.
3.The sum of the currents through each path is equal to the total current that flows from the source.
4.You can find total resistance in a Parallel circuit with the following formula:
1/Rt = 1/R1 + 1/R2 + 1/R3 +...
Rt = R (t)otal
5.If one of the parallel paths is broken, current will continue to flow in all the other paths.


A series circuit has certain characteristics and basic rules:

1.The same current flows through each part of a series circuit.
2.The total resistance of a series circuit is equal to the sum of individual resistances.
3.Voltage applied to a series circuit is equal to the sum of the individual voltage drops.
4.The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor.
5.If the circuit is broken at any point, no current will flow.

Answer 2

$\huge \bold{ANSWER}$

$\bold{IN \: SERIES }$

In series combination the resistors are joined one after other.

The following facts can be noted :--

◼The current has a single path for its flow.Hence same current passes through each resistor, so the potential difference across any resistor is directly proportional to its resistance. Thus the potential difference is different across the different resistances.

◼The potential difference across the entire circuit is equal to the sum of the potential differences across the individual resistor.

$V=V_1 +V_2 +V_3+n$

◼Equivalent resistance will be

$R=R_1 +R_2 +R_3+n$

$\bold{IN \: PARALLEL }$

In parallel combination, one end of each resistor is connected at one point and other end to other point.

The following facts can be noted :--

◼The same potential difference across each resistor is same which is equal to potential difference across the terminal of the battery or source.

◼The current in a resistor is inversely proportional to its resistance. The sum of currents in the seperate branches of the parallel circuit is equal to the total current I drawn from the source.

$I = I_1 + I_2 +I_3+n$

◼Equivalent resistance will be

$R=\frac{1}{R_1} +\frac{1}{R_2} +\frac{1}{R_3}+n$
