Question

Two resistors of 10 ohm each are connected in parallel the equivalent resistance ?

Answer 1

Explanation:

let two resistor R1=R2=10

1/R = 1/R1 + 1/R2

1/R = 1/10 + 1/10

1/R = (1 +1)/10

1/R = 2/10

1/R = 1/5

R = 5 ohm

Answer 2

Electric Current

Two resistors of 10 ohm are connected in parallel.

• We know that when two resistors are connected in parallel, potential difference across all the resistors remains same.
• The supply current is equal to sum of all the currents through each resistors.

To calculate the total overall resistance of a of two resistors connected in this way we use formula:

$R_{total}=\frac{R_1\times R_2}{R_1+R_2}$

Where R₁  and R₂ are two resistors connected in parallel.

$R_{total}=\frac{10\times10}{10+10}=5\ ohm$

Hence total resistance will be 5 ohm.
