1) To find the current level, we can use Ohm's Law: V = IR, where V is the voltage drop, I is the current, and R is the total resistance.

Given:
V = 12V
R = 5.6kΩ = 5600Ω

Using Ohm's Law:
12 = I * 5600
I = 12 / 5600
I ≈ 0.00214 A

Therefore, the current level is approximately 0.00214 A.

2) To find the power delivered, we can use the formula: P = IV, where P is power, I is current, and V is voltage.

Given:
I = 0.00214 A
V = 12V

Using the formula:
P = 0.00214 * 12
P ≈ 0.0257 W

Therefore, the power delivered is approximately 0.0257 W.

3) To find the energy dissipated in 1 hour, we can use the formula: E = P * t, where E is energy, P is power, and t is time.

Given:
P = 0.0257 W
t = 1 hour = 3600 seconds

Using the formula:
E = 0.0257 * 3600
E ≈ 92.52 J

Therefore, the energy dissipated in 1 hour is approximately 92.52 Joules.
