Q:

How many volts are in 1 amp?

A:

Amps do not contain any volts. Volts and amps are two different types of electrical properties, and one does not contain the other. A relationship does exist between volts and amps, and Ohm's Law defines that relationship.

Volts are a measure of the electrical potential between one point and another, such as between the two slots in a wall outlet. Amps (amperes) are a measure of the flow of electric current. If there is an electric circuit that features a resistive element, such as the element in a heater, the current flowing through that element is equal to the voltage across the element divided by the resistance of the element. This relationship is Ohm's law: I = E/R, sometimes expressed as E = IR, where E is volts, I is amps, and R is resistance.

  • Q:

    How many volts equal one amp?

    A:

    Because these two terms measure two different aspects of electricity, it is not possible to convert between the two. Amperage is a measure of current flow past a given point, while voltage is the potential for current flow.

  • Q:

    How many volts does a joule equal?

    A:

    Volts cannot be directly converted into joules. The energy in joules is equal to the voltage in volts times the electrical charge in coulombs. A coulomb is a fundamental unit of electrical charge, and it is the charge transported by a constant current of 1 ampere in one second.

  • Q:

    How many watts make one amp?

    A:

    Power in watts equals amperes times voltage. So, in a direct current, 1 amp at 110 volts equals 110 watts, whereas 1 amp at 220 volts equals 220 watts.

    How many teaspoons does 5 grams contain?

    A:

    The number of teaspoons to grams differs depending on density of the substance. While 1 teaspoon of sugar is equivalent to about 4 grams, 1 teaspoon of salt is about 6 grams. A gram of water is equal to 0.2 teaspoon, so 5 grams of water equals 1 teaspoon.
