Describe Ohm's law and its limitations;

1 answer:

5 0

The Ohm's Law is a powerful and simple tool to analyze electric circuits. It shows the relationship between voltage (V) and current (I) in a conductor. But, in order to properly apply to circuits (real circuits), its limitations must be understood. Most conductors, resistance is greatly unaffected by current or voltage (resistance is stable property).
Limitation: this law does not apply to rectifiers or semiconductors or to the conduction of electricity through gases.
Formula: current (I) is equal to voltage (V) over resistance (R)

jason hits a baseball off a tee toward right field. the ball has a horizontal velocity of 10 m/s and lands 5 meters from the tee

Leni [432]

Answer:

The height is 1,225 meters

Explanation:

DistanceX= speedX × time ⇒ time= (5 meters) ÷ (10 meters/second) = 0,5 seconds

DistanceY= high= (1/2) × g × (time^2) = (1/2) × 9,8 (meters/(second^2)) × 0,25 (second^2) = 1,225 meters
