Question

To increase the effective resistance in a circuit the resisitor are connected in ?

Answer 1

Answer:

series

Explanation:

Answer 2

Hey !!



First consider the formulae

Effective Resistance Formula :

If we have n number of Resitors

In series connection:

$R_{e} = R_{1}+ R_{2}+ \cdots R_{n}$

In parallel connection:

$\frac{1}{R_{e}} = \frac{1}{R_{1}} + \frac{1}{R_{2}} +\cdots + \frac{1}{R_{n}}$

$\\ \:$

If we have 2 Resistors:

In series connection:

$R_{e} = R_{1}+ R_{2}$

In parallel connection:

$\frac{1}{R_{e}} = \frac{1}{R_{1}} + \frac{1}{R_{2}}$

$\frac{1}{R_{e}} = \frac{R_{1}\times R_{2}}{R_{1}+R_{2}}$

•°• For parallel circuits, the effective Resistance is always be less than the smallest resistance for each path.

So series connection has more effective Resistance.

To increase the effective resistance in a circuit the resisitor are connected in $\huge{\underline{\textsf{Series}}}$
