Answer:
Heater 2 will give off more heat.
Explanation:
The heat given off by the heaters can be found out by the following formula:
[tex]Q = VIt[/tex]
but, from Ohm's Law:
[tex]V = IR\\\\I = \frac{V}{R}[/tex]
Therefore,
[tex]Q = \frac{V^2t}{R}[/tex]
where,
Q = heat given off by the heater
V = Voltage
t = time
R = Resistance
It is clear from the equation that for a constant voltage and time, the heat given off by the heater is inversely proportional to the resistance of the heater.
Heater 2 will give off more heat.
Therefore, the heater with lower resistance will give off more heat.
