Power Voltage Current Calculator

Whereas in alternating current electric charge in alternating current changes direction periodically.

Power voltage current calculator. For single phase connection voltage can be mathematically derived from this below formula for three phase connection voltage can be mathematically derived from this below formula. In direct current the electric charge flows in only one direction. Learn the power formula. If there is ac look also at the power factor pf cos φ and φ power factor angle phase angle between voltage and amperage.

The voltage v in volts v is equal to the current i in amps a times the resistance r in ohms ω. This page shows the online ac power calculator to calculate the ac current in a circuit for the given power factor angle voltage current etc. The voltage v in volts v is equal to the square root of the power p in watts w times the resistance r in ohms ω. But we have designed this one especially for dc circuits as well as work for single phase ac circuits without power factor.

Power voltage current resistance p v i r calculator. V v i a r ω. Voltage volts current amps x resistance ω. Power p voltage v current i.

Voltage calculator is also used in electrical engineering to measure the unknown voltage by two known quantities kva and current applied to the below formulas. The above calculator will help you to calculate the power using a simple power formula. If voltage and current are given then you can easily calculate the value of the power. The power p in watts w is equal to the voltage v in volts v times the current i in amps a.

In the above circuit we know we have a battery voltage of 18 volts and a lamp resistance of 3 ω. We ve seen the formula for determining the power in an electric circuit. The power p in watts w is equal to the voltage v in volts v times the current i in amps a. How to calculate power.

The power p in watts w is equal to the squared voltage v in volts v divided by the resistance r in ohms ω. Power p i v r i 2 v 2 r where power p is in watts voltage v is in volts and current i is in amperes dc. How to use ohm s law to determine current. V 10 ma x 15 kω.

By multiplying the voltage in volts by the current in amps we arrive at an answer in watts let s apply this to a circuit example.
