Assuming 100% efficiency P=IV Power = 120 x 20 = 2400WPower = Energy/ timeIn 1 second Energy used in lifting= 2400J Energy = Force x displacement Displacement in 1 second = 10m Force= mass x gravitational field strength = mg Taking g = 10 N/kg Energy = mgh where h is height (or displacement) 2400= m 10(10) 2400 = 100m m = 24 kg

Current is measured in?
The unit of electrical current is the Ampere. 1 Ampere = 1 Coulomb per second.
What is the relation between the amount of electric current passed and the heat produced?
The relation is:P = I2RWhere:I is the current (for example, in amperes)R is the resistance (for example, in ohms)P is the power (energy per second) converted from electrical energy to heat. If the current is in amperes and the resistance in ohms, then power is in watts (equal to joules/second).
A charge of 15 Coulomb flows through any area in a circuit each second the current is?
15 ampere. Since current = charge / time
Steady flow of electrons?
elelctric current
What is meant by the terms electric current?
Current is the amount of electrical charge that flows past a given point in a given time. Current is measured in Amperes, which is Coulombs per Second. Sometimes, erroneously, we use the term current to refer to voltage or power. Voltage is Joules per Coulomb. Power is Joules per Second, or Voltage times Current.
What is the unit for current?
Amperes. This is often shortened to Amps and is abbreviated as A.
What can you measure with amperes?
Current is measured in amperes. Amperes is also coulombs per second.
The amount of current per second amperes per second is a?
Base unit delta current
How much current flows through a circuit if 2 coulombs of charge flows each second?
Current in amperes is coulombs per second, so 2 coulombs per second is 2 amperes.
What unit is current measure in?
Electrical currents are measured in a unit called amperes, which are abbreviated as "amps." There are two different designations that measure currents: direct currents (DC) and alternating currents (AC). Amperes are coulombs per second. Amperes are electrical current units that are part of the meter-kilogram-second system. A flow of one coulomb per second is equivalent to one single ampere.
What is the definition of a current?
Current is electrical charge flow, in coulombs per second. We simplify coulombs per second and call it amperes.
What can electric current be measured by?
Electric current is measured in amperes. 1 ampere = 1 coulomb/second
What is an eletric current measured in?
If you refer to the units, power (any power, not just electrical power) is energy divided by time. The SI unit is the watt, equal to 1 joule/second.
How are voltage and current measured?
ElectricalElectrical current is measured with an ammeter and in units called amperes, or amps.Stream FlowRiver flow or current (discharge) is measured in cubic feet per second or cubic meters per second.
Current is measured in?
The unit of electrical current is the Ampere. 1 Ampere = 1 Coulomb per second.
The ampere is the unit of electric current in the metric system The amount of current per second amperes per second is a?
A coulomb is the quantity of charge displaced by a one ampere per second.
The unit for current is?
Current is measured in amperes, or amps for short (A). One ampere equals one coulomb of charge per second.
