Question

Ten 10Ω resistors are connected in parallel. What will be its net resistance?

Answer 1

Answer:

1 ohm

Explanation:

Just put the values in the formulae..... Or R/N...... A simple equation.

Means 10/10(R/N) formulae..... However if it is difficult for you., so you can apply the simple formulae to find resistance for parallel connections. That is

1/Rp=1/R1 +1/R2+1/R3............

Answer 2

Answer:

The equivalent resistance = 1Ω

GIVEN :

Ten 10Ω resistors are connected in parallel.

TO FIND:

Equivalent resistance when they are connected in Parallel.

SOLUTION:

$when \: n \: resistors \: of \: same \: resistance \: \\ are \: connected \: in \: parallel \: then \: equivalent \\ resistance \: is \: \: ( \frac{r}{n} ) \\ \\ \\ here \: \: n = \: 10 \: \: \\ \\ ten \: 10Ω \: resistor \: are \: connected \: in \: parallel. \\ \\ equivalent \: resistance \: = \frac{10}{10} \\ \\ equivalent \: resistance \: = \: 1Ω \\ \\ \\ ......................................... \\ \\ \\ some \: important \: formulas \\ \\ when \: n \: resistors \: of \: same \: resistance \: \\ are \: connected \: in \: parallel \: then \: equivalent \\ resistance \: is \: \: ( \frac{r}{n} ) \\ \\ \\ when \: n \: resistors \: of \: same \: resistance \: \\ are \: connected \: in \: series \: \: then \: equivalent \\ resistance \: is \: \: ( rn)$
