Electric Pressure Current And Resistance Answer Key
The electric potential difference across a light bulb or any resistor in an electric circuit is simply the product of the current at that bulb multiplied by the resistance of the bulb.
Electric pressure current and resistance answer key. However when the voltage exceeds the air s ionization potential the air becomes a good conductor of electricity its electrical resistance decreases dramatically resulting in a transient current as the accumulated electric charge dissipates in the form of a lightning bolt. Navigate to the dc circuit builder interactive at the physics classroom. The actual answers will be shown in brackets followed by an explanation. Physics 6 electric current and circuits.
The purpose of this activity is to determine the mathematical relationship between battery voltage av current i and resistance r for a simply circuit. Each bulb has the same resistance since they re identical and the same current since the current is everywhere the same. If you don t understand an explanation that is given in this section you may want to go back and review the lesson that the question came from.
