The thermal energy is produced in 7.5 minutes will be 2×10² J.
Electrical energy is turned into heat energy when a current travels across a resistor.
The heat created in a circuit's components, all of which have some resistance, is dissipated into the air around the components.
The given data in the problem is;
R si the resistance = 50-ω resistor
V is the volatage=9.0 V
t is the time period= 7.5 minutes=0.125 sec
From ohm's law;
V=IR
90=I×50
I=0.18 A
The thermal energy generated in the resistor is given as;
H=I²Rt
H=(0.18)²×50×0.125
H=2× 10² J
Hence the thermal energy is produced in 7.5 minutes will be 2×10² J.
