The power in a lightbulb is given by the equation p = r, where i is the current flowing through the lightbulb and r is the resistance of the lightbulb. what is the current in a circuit that has a resistance of 30.0 (look at image attached for symbol) and a power of 55.0 w? ? a. 1.83 a b. 0.740 a c. 1.35 a d. 0.550 a

Answer

1.35 A

Explanation

Power is the rate of doing work. It is given by:

Power = I²R

Power = 55.0 W and resistance = 30.0Ω

55.0 = I² × 30.0

I² = 55/30

  = 1.833333

I = √1.83333

 = 1.35 A

the answer is d

explanation:

dan realized that his goal of going to an ivy league school if only he works hard which means basically this   to become completely aware of (something) as a fact; understand without a doubt to make (something desired or anticipated) occur to give real, definite or physical form to a plan, dream, or goal to earn (money or a profit) from a deal

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
