Question

Two resistors of resistance
2 ohms and 4 ohms are
connected in parallel to a 6 volt
battery. Find the heat dissipated
in the 4 ohm resistor in 5 seconds

Answer 1

Answer:

45 joules of heat dissipated by ohm resistor

Step-by-step explanation:

according to ohm's law

I=V/R

given,

I =? , We need to find it

V=6 volt

R=4 ohm

I=6/4

power = volt×Ampere

power=6/4×6=9 watts of power

resistor dissipate 9w of power in one second

for 5 second ,

power=energy/time

energy=9×5=45 joule

there 4 resistor dissipate 45 joule of heat in 5 second on 6 volt.
