Convert what quantity From: abampere ampere amp biot centiampere coulomb/second deciampere dekaampere electromagnetic unit of current electrostatic unit of current franklin/second gaussian electric current gigaampere gilbert hectoampere kiloampere megaampere microampere milliampere milliamp nanoampere picoampere. In relation to the base unit of => (watts), 1 Milliwatts (mW) is equal to 0.001 watts, while 1 Volt Ampere (VA) = 1 watts. How to convert Milliwatts to Volt Ampere (mW to VA)?Īlways check the results rounding errors may occur. V(V) (P(W) × R()) The voltage V in volts (V) is equal to the square root of the power P in watts (W), multiplied by the resistance R in ohms (). ![]() RLC Resonance frequency calculator: A useful electronics tool for finding the frequency at which a circuit resonates.The base unit for power is watts (Derived SI Unit) ![]() Solution: I = / = 80.28 Aģ Phase Induction Motor current calculator: A useful calculator to find the FLA and RLA in 3 phase induction motorĮlectricity bill calculator: Used to find the cost of appliances in your bill.Ĥ Band Resistor color code calculator: A useful tool for decoding 4 band resistors.ĥ Band Resistor color coding calculator: Provides the value of 4 band resistor. Find the current if the power factor is 0.9. Three phase kW to Amps calculations involve a ration of 1000 times kW to the power factor times voltage and an additional factor 1.73 that represents an equivalent of √3 and is added because the circuit is three phase in nature.Įxample: A 3 phase 400 volt circuit has a 50 kW load connected to it. Solution: I = / = 31.25 A Three phase kW to Amps Volts to Amps calculation with ohms Enter the voltage in volts (V), resistance in ohms (), then press the Calculate button to get the result in amps (A). V(V) P(W) / I(A) The voltage V in volts (V) is equal to the power P in watts (W), divided by the phase current I in amps (A). Calculate A: 0 I(A) P(W) / V(V) The current I in amps (A) is equal to the power P in watts (W), divided by the voltage V in volts (V). For example, let’s calculate the amperage of a 100-watt light bulb at 120 volts. Enter the power in watts (W), current in amps (A), then press the Calculate button to get the result in volts (V). Here the formula is identical to the previous one with the difference being a 2 is introduced in the denominator.Įxample: A 200 volt, two-phase circuit operating at 0.8 PF is loaded with 10 kW load. I(A) P (W) V (V) So, the current I in amps is equal to the power P in watts divided by the voltage V in volts. Solution: I = / = 196 A Two-phase kW to Amps The system is operating at 0.85 power factor. Single phase formula is a ration of thousand times kilowatts to the power factor times operating voltages.Įxample: A 120-volt single phase AC circuit has 20 kW load. Amps to volts calculation with ohms Enter the current in amps (A), resistance in ohms (), then press the Calculate button to get the result in volts (V). Thus, the AC24-40 can supply up to 1.6 Amps at. Calculate Volts: 0 V(V) P(W) / I(A) The voltage V in volts (V) is equal to the power P in watts (W), divided by the phase current I in amps (A). Enter 24 under volts Enter 40 under watts Click calculate You get 1.66 in this example. then R ( V / i ' ) - G ' 1 Volt 1 amp where i'g maximum current for. The AC24-40 power supply is a 24V AC power supply that can power up to 40 VA. Conversion of Ammeter into Voltmeter : IfR is high resistance required to be. Fill in the Volts and Amps fields to find the Watts. The single phase and all other alternating current circuits introduce an additional concept of power factor in the denominator. You have a 12 Volt power supply that delivers 1 Amp of current. ![]() Amps measure the flow of electricity as an electric current. Amp hours the shortened name of ampere-hour indicates how much charge can flow through a battery per one hour. How to convert Amps to Watts Amps x Volts Watts. Solution: I = / 100 = 500 A Single phase kW to Amps Our watt hour calculator allows you to use electric charge in milliamp or amp hours and voltage in volts to calculate the energy in watt-hours or joules. It is a ratio of 1000 times kW to the system voltages.Įxample: A 50 kW, 100-volt dc (Direct current) generator power v belt at a cement production power plant. ![]()
