Question

200 V is applied across a 100 ohm resistor for 5 minute.

200 V is applied across a 100 ohm resistor for 5 minute.

a) How much is the heat developed in the circuit


​

Answer 1

Potential Difference =200v,

Resistance =100 ohm,

Time= 5min,

Time =300 second

$V=IR$

$200=I×100$

${\boxed{I=2 Amp.}}$

Now,

$\huge\green{\mathbb{H=I^2RT}}$

$H=(2)^2×100×300$

$H=4×30000$

$\huge\purple{\boxed{H=120000Joule}}$
