Answer:

150A

Explanation:

Given parameters:

Potential difference = 120V

Resistance = 0.8Ω

Unknown:

Current = ?

Solution:

From ohm's law;

I = $\frac{V}{R}$

I is the current

V is the voltage

R is the resistance

Now insert the parameters and solve;

I = $\frac{120}{0.8}$ = 150A

leonid [27]

<h2>Energy used by heater is 8.21 x 10⁶ J</h2>

Explanation:

Energy = Power x Time

Power = Voltage x Current

Voltage = 120 V

Current = 9.5 A

Power = Voltage x Current

Power = 120 x 9.5 = 1140 W

Time = 2 hours = 2 x 60 x 60 = 7200 s

Energy = Power x Time

Energy = 1140 x 7200

Energy = 8208000 J

Energy used by heater is 8.21 x 10⁶ J
