KVPY SB SX Exam 2011 Question Paper

Question : 33 of 120

Marks: +1, -0

In the circuit shown below the resistances are given in ohms and the battery is assumed ideal with emf equal to 3.0 volts. The resistor that dissipates the most power is

$R_1$
$R_2$
$R_3$
$R_4$

Validate

Solution:

Power dissipate in

\R_1

is maximum as its current is maximum and its resistance is also 40Ω which is higher than

\R_5\R_4
