Question

calculate equivalent resistance of three resistances connected in parallel

Answer 1

Answer:

• 1/Req = 1/R1 + 1/R2 + 1/R3

Explanation:

Solution:-

Total Number of Resistor = 3

Let the

• Resistance of 1st Resistor = R1

• Resistance of 2nd Resistor = R2

• Resistance of 3rd Resistor = R3.

As we know that if we connect resistors in Parallel then the Equivalent resistance will be the sum of reciprocal of individuals Resistor .

• 1/Req = 1/R1 + 1/R2 + 1/R3 + ...

Additional Information !!

•Potential Difference: The potential difference between two point in an electric circuit carrying some current as the work done to move a unit charge from one point to the other.

Potential difference = Work done /Charge.

• V = W/Q

here

• V is the potential difference
• W is the work done
• Q is the charge

• SI unit of electric potential energy is volt (V).

• 1 volt : The potential difference between two points in a current carrying conductor when one joule of work is done to move a charge of one coulomb from one point to other.

•1 Volt = 1Joule/1Coulomb

Answer 2

Answer:

Solution :-

When three resistance are connected in parallel series then the formula will be

$\huge \tt \: \frac{1}{Req} = \frac{1}{R1} + \frac{1}{R 2}+ \frac{1}{R3}$

Here

Req is the Required resistance

R1 is the first resistance

R2 is the second resistance

R3 is the third resistance
