Power = 600/30 = 20 watts
Power = V x I
V = Power/I = 20/2 = 10 volts

What is the role of voltage in an electrical circuit?
Voltage is related to energy by charge. Power equals voltage times current (amperes), and energy equals voltage times charge (coulombs).An ampere is 1 coulomb of charge moving per second.A watt (power) is 1 joule of work done (or energy transferred) per second.
Is current measured in volts?
The Ampere is the unit of electric current. It depends upon a voltage in order for it to occur, and the Volt is that unit. The Ohm is the unit of resistance and represents the difficulty of moving the electrons by the voltage.
When electricity leaves the power plant it is measured in what unit?
There are lots of different units for electricity, depending what aspect you want to measure (power, energy, current, voltage, frequency, etc.).For a power plant, some relevant units include: * Volt, for voltage * Ampere, for current * Watt, for power * Hertz, for frequency
Can you calculate power by multiplying voltage and current?
Not enough information. Power = current x voltage. Since voltage can be anything, there is no way to calculate power. Time is irrelevant; though once you have the power, it can help you calculate energy (energy = power x time).
How could a capacitor have voltage but no current?
Voltage and current are two different things. Voltage is potential energy per charge, in joules per coulomb, while current is charge transfer rate, in coulombs per second. Its that same as saying that a battery has voltage but no current, because there is no load. Well, a capacitor resists a change in voltage by requiring a current to change the voltage. Once that voltage is achieved, there is infinite resistance to the voltage, and thus no current.
How many volts in a 9000 mAh battery?
The number of Ah (ampere-hours) or milli-ampere-hours tells you NOTHING about the voltage. It is the amount of current (amperes), multiplied by the time such a current can be extracted from the battery.If you multiply the number of Ah by the voltage, you will get the energy stored in the battery.
How is battery voltage related to electrical energy?
Voltage is the amount of energy in each coulomb of charge that passes through the battery. This means that the energy is the voltage times the time-integral of the current. For a constant current: E = V I t Where E = Energy in Joules V = Voltage in Volts I = Current in Amps t = time in seconds

How many AH equals to 1KVA?
You really can't compare that. * Ampere-hour is a unit of energy. If you multiply ampere x hours x voltage (the voltage is implied), you get energy. * kVA is a unit of power. Note that power is energy / time.
How many amps equal one amp hour?
You can't convert amperes to ampere-hours, for the same reason that you can't (for example) convert kilometers to kilometers per hour, meters to square meters, etc. Those are, quite simply, incompatible units. An ampere is a unit of electrical current; an ampere-hour is really a unit of energy: the energy stored when a current of 1 ampere flows during one hour. To actually be an energy unit, a voltage must be assumed; this is usually 12 volt for a car battery.
What is the amount of electric energy supplied if the current and voltage are doubled?
Energy is measured in the SI unit Joule. One definition of a Joule is one ampere passing through a resistance of one ohm for one second. Thus doubling the electrical current (amperes/amps) passing through a resistance of one ohm for one second will double the energy. As for voltage, given that voltage (volts) = current (amps) times resistance (ohms) then, assuming a constant resistance, the voltage will double if the current doubles. Thus doubling the voltage (and therefore the current) passing through a resistance of one ohm for one second will double the energy (joules).
How many amperes a 1.5 ton ac consumes in 1 hour?
I am not sure what you mean, but ampere is a unit of current, not of energy. In the case of a constant current, if the current is 1 ampere in a second, it will be 1 ampere in an hour, or in a day.
How do you convert Volt Ampere into Joules?
You can't. If you know the voltage (volts) and current (amperes), you can convert to power (watts), but power is not energy. Power is the rate of energy (joules per second). You need to know the time as well to determine energy.
1 kilowatt hours equal to how much ampere?
You can't convert that directly. kWh is a unit of energy; ampere is a unit of current.
Energy carried by current?
For DC: power (in watts) = current (in ampere) x voltage (in volts). Energy = power x time, so energy = current x voltage x time (time in seconds). For AC, a power factor may have to be included (the cosine of the angular displacement between current and voltage). This is often near one, but it may be less.
Definition of voltage?
Voltage is electrical pressure, in joules per coulomb. One volt across one ohm will yield a current of one ampere, which is coulombs per second. One volt, producing one ampere, will yield one watt, which is joules per second.
