Question

if 3 resistance of 3 ohm each are connected in parallel ,with will be their total resistance

Given

3 resistance of 3 ohm are connected in parallel arrangement...

To find

total resistance

Solutions

☄️A circuit is said to be connected in parallel when the voltage is the same across the resistors.

☄️The following relation gives the total resistance of a parallel circuit.

$\large \bold{ \to\frac{1}{ R_{eq}} = \frac{1}{ R_{1}} + \frac{1}{ R_{2}} + .......+ \frac{1}{ R_{n} } }$

Now substitute the values in the above formula:

$\to \bold{ \frac{1}{R_{eq}} = \frac{1}{ 3} + \frac{1}{ 3} + \frac{1}{ 3 } } \\ \\ \to \bold{ \frac{1}{R_{eq}} = \frac{3}{ 3} = 1} \\ \\ \bold \purple{\to \: R_{eq} = 1 \: ohm}$

↬therefore the resistance in the circuit will be 1 ohm if 3 resistors of 3 ohm are connected in parallel arrangement.

MoRE information!!!

✏️A circuit is composed of conductors (wire), power source, load, resistor and switch.

✏️Resistors control the flow of the electric current in a circuit.

✏️A circuit is said to be connected in series when the same amount of current flows through the resistors.

✏️The following relation gives the total resistance of a series circuit:

$\bold {➙R_{eq} = R_{1} + R_{2} + R_{3} + .... + R_{n}}$
