Power Related To Voltage And Current

Direct current voltage source such as 5v 12v 24v etc in electronic circuits and systems.

Power related to voltage and current. In this video what is voltage current and power in electrical circuits are explained in a simplistic manner and how they are related to each other. The unit for power is the watt w which is equal to a joule per second this relation can be found from the formula for power the power used or dissipated by a resistor can be found using the formula v ir. This formula can be used to substitute for the voltage or for the current in the power formula and. Learners examine a series parallel circuit and solve 14 problems related to voltage current and power.

Current voltage and power. The amount of current in a circuit depends on the amount of voltage and the amount of resistance in the circuit to oppose current flow. Think of voltage as the flow rate or speed of the water. A help screen is provided.

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 i is the rate of flow of charge carriers such as electrons current is usually thought of as moving in the direction of positive charge so from the positive power supply to the negative. 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. These include the quantities current voltage and power.

The faster the water is flowing higher the pressure can be equated to voltage. Watch now 114 29 8k flash. Batteries or power supplies are mostly used to produce a steady d c. For this reason the quantities of voltage and resistance are often stated as being between or across two points in a circuit.

Match the exponent or radical to its equivalent. Just like voltage resistance is a quantity relative between two points. Alternating current voltage sources are available for domestic house and industrial power and lighting as well as power transmission. Think of power as total volume of water being pumped into a bucket.
