Relationship Between Power Voltage And Current
Learners examine three formulas than can be used to find dc power.
Relationship between power voltage and current. The relationship between voltage current and resistance forms the basis of ohm s law. The best analogy is a garden hose. Relationship between voltage and current. The faster the water is flowing higher the pressure can be equated to voltage.
The relationship of voltage current and watts by patrick hoppe. Start studying what is the relationship between power voltage and current. That is if the voltage doubles the current doubles too. Power p voltage v current i that law describes the relationship between power voltage and current in a conductor it means that if you measure the current flowing in the conductor and you measure the voltage difference from one end of the conductor to the other at the same instant then the product of voltage and current will be the rate at which heat is generated in the conductor at.
Current and voltage are two fundamental quantities in electricity voltage is the cause and current is the effect. Think of voltage as the flow rate or speed of the water. Regardless of what the voltage and current waveforms look like and regardless of the phase angle between them instantaneous power instantaneous voltage x instantaneous current when the unit for instantaneous voltage is volts and the unit. By the same token if the resistance of the resistor does not change then if the voltage drops in value decreases the current also decreases.
Learn vocabulary terms and more with flashcards games and other study tools. In a linear circuit of fixed resistance if we increase the voltage the current goes up and similarly if we decrease the voltage the current goes down. The relationship between the voltage across a resistor and the current through that resistor is linear.
