In a simple circuit, the amount of voltage, and the resistance of the load. Amps = volts / ohms.
For a motor, the back EMF when the rotor is turning reduces the effective voltage across the windings, reducing the current. That is why a motor may burn out if it is powered but cannot turn.

What 2 factors does the energy use on an electric bill depend on?
How long you leave the power switched on, and the amount of power (ie rate of use of energy) delivered when it is swirched on.
What two factors determines the intensity of a sound?
The intensity of a sound is determined by the rate and density of energy transfer. The larger the amplitude, the greater the intensity, and the louder the sound.
What determines your acceleration?
The rate that your speed increases or decreases.
What is the rate at which electrical current is converted to another form of energy?
The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts.
Does the mass of an object determines the rate at which it will fall?
Mass does not determine the rate something will fall. The rate of acceleration is constant as gravity, regardless of mass.
Which gland determines the rate of which the human body uses energy?
Thyroid gland determines the rate at which human body utilizes energy.
Which determines the rate at which a solid dissolves in a liquid solvent?
the frequency and energy of the collisions between the solute and solvent particles
The current refinance mortgage rate is calculated using a formula that is determined by what organization?
There is no specific organization that determines the current refinance mortgage rate, however there are ways to calculate whether or not one should refinance on online calculators.
What determines the amount of current a voltaic cell can produce?
Thew rate of corrosion determine the amount of current of a voltaic cell OR the potential difference of the two materials. --- R.B.DHRUV

The difference between energy and power in circuit?
Energy is measured in Joules(J). Power is measured in Watts(W). 1 W = 1 J/Second. Power is the rate at which energy is delivered.
What determines the rate of fermentation?
The verga!
What determines the current money market rates?
Current money markets rates are mostly based on current stock market prices. It goes up and down daily so you can check your bank often in order to get a good rate locked in.
Why does alternating current allow power transmission?
First of all, it's energy that's being transmitted, not power! Power merely tells us the rate at which energy is being transmitted.Next, it's a complete misconception to think that energy is delivered by electrons which, then, return to the source to collect more energy -rather like a conveyor belt! Electrons move far too slowly for that to happen (an individual electron is unlikely to travel the length of a flashlight's filament before the battery runs down!). It's far more likely that energy is delivered in the space around (rather than through) the supply wires due to a combination of the electric and magnetic fields, called the 'Poynting Field' (check this out on the internet).Finally, if we think of 'positive' power as the rate at which energy is being transmitted in the 'forward' direction (i.e. from the source to the user) then, during the negative half-cycles of a.c. current and voltage, the product (P =EI) is still positive. So it matters not whether it is being 'delivered' by d.c. or a.c.
What determines the rate of weathering?
weathering and erosion
Who determines interest rate in banks?
inflation
