Well, first of all, if the resistance of the circuit is 10 ohms and you connect 10 volts to it,
then the current is 1 Amp, not 2 . So either there's something else in your circuit that
you're not telling us about, or else the circuit simply doesn't exist.
-- If you connect some voltage to some resistance, then the resistance heats up and
dissipates (voltage)2/resistancewatts of power, and the power supply has to supply it.
-- If there is some current flowing through some resistance, then the resistance heats up and
dissipates (current)2 x (resistance)watts of power, and the power supply has to supply it.
-- If there's a circuit with some voltage connected to it and some current flowing
through it, then the resistance of the circuit is (voltage)/(current) ohms, the parts
in the circuit heat up and dissipate (voltage) x (current) watts of power, and
the power supply has to supply it.
There's no such thing as "the power of a circuit". The power supply supplies the
circuit with some amount of power, the circuit either dissipates or radiates some
amount of power, and the two amounts are equal.
What else can I help you with?
How any amps in 65 Watts 240 power supply?
To calculate the current (in amps), you can use the formula: Current (Amps) = Power (Watts) / Voltage (Volts). In this case, if you have a 65-watt power supply with a voltage of 240 volts, the current would be 0.27 amps.
What is the amperage of a standard power outlet in China?
10 amps 250 volts or 16 amps 250 volts.
How do you work out 9 volts and current 0.02 amps?
To calculate power, multiply voltage (9 volts) by current (0.02 amps): 9 volts * 0.02 amps = 0.18 watts.
How many watts does 20 amps at 240 volts produce?
The unit of power is expressed in watts, and the product of current (Amps) and voltage (volts) is power there fore if you multiply the amps and the volts give watts. so 20 x 240 will give you a 4800 watts of power.
How many watts are in 60 amps at 115 volts?
The formula you are looking for is W = Amps x Volts.
Using 120 volts at 12 amps is the same power as what amps at 220 volts?
6 amps.
How do volts get power?
Volts cause current to flow through the load. The current is measured in amps, and the volts multiplied by the amps gives the power in watts.
How any amps in 65 Watts 240 power supply?
To calculate the current (in amps), you can use the formula: Current (Amps) = Power (Watts) / Voltage (Volts). In this case, if you have a 65-watt power supply with a voltage of 240 volts, the current would be 0.27 amps.
What is the amperage of a standard power outlet in China?
10 amps 250 volts or 16 amps 250 volts.
How do you work out 9 volts and current 0.02 amps?
To calculate power, multiply voltage (9 volts) by current (0.02 amps): 9 volts * 0.02 amps = 0.18 watts.
What is the capacity of 1.5kva?
a 1.5 kVa source of electrical power has the capacity to supply 100 volts at 15 amps, 300 volts at 5 amps, or 1000 volts at 1.5 amps.
What is the formula to convert amps to volts?
Amps and volts are two separate parts of power measurement and do not convert into each other. Multiplying amps times volts will give you the measurement of wattage.
How many watts does 20 amps at 240 volts produce?
The unit of power is expressed in watts, and the product of current (Amps) and voltage (volts) is power there fore if you multiply the amps and the volts give watts. so 20 x 240 will give you a 4800 watts of power.
How many watts are in 60 amps at 115 volts?
The formula you are looking for is W = Amps x Volts.
How many milliamps in 48.8 watts?
Milli amps is a measure of current whilst watt is a measure of power. The missing element is voltage as the formula is:- Power = Voltage * Amps ie power in Watts is the product of Volts (in Volts) times Amps (in Amps)
How many watts is 7 amps at twelve volts?
"Power (/Watts) = Current (/amps) * Potential Difference (/volts)" Therefore, power = 7 * 12 = 84 W
How many amps are in 280 watts with 120 volts?
W = Amps times Volts. A = W/V, A = 300/120 = 2.5 amps
