In a direct current (DC) circuit, electrical power is proportional to both voltage and current according to the equation P = V * I, where P is power, V is voltage, and I is current. This relationship dictates that as either voltage or current increases, electrical power will also increase.
Acceleration is directly proportional to the force applied to an object and inversely proportional to the mass of the object. This means that increasing the force applied will increase the acceleration, while increasing the mass will decrease the acceleration for a given force.
False. The strength of an electrical signal is not directly proportional to its frequency. The strength of an electrical signal is related to its amplitude, which is the height of the signal. Frequency, on the other hand, refers to the number of cycles of the signal that occur in a given unit of time.
Coulomb's law is a fundamental rule that applies to the action of electrical charges. It states that the force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
In an electrical circuit, current is directly proportional to voltage and inversely proportional to resistance. This relationship is described by Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R), or I V/R.
The force of gravity between two masses is always attractive, proportional to the product of the masses and inversely proportional to the square of the distance between them. In contrast, the electric force between two charges can be attractive or repulsive, depending on the signs of the charges, and is proportional to the product of the charges and inversely proportional to the square of the distance between them.
Yes. It is directly proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between them.

Acceleration is directly proportional to the force applied to an object and inversely proportional to the mass of the object. This means that increasing the force applied will increase the acceleration, while increasing the mass will decrease the acceleration for a given force.
Power (watts) is amperes times voltage, or joules per second. Energy is joules, or watt-seconds. The length of time an electrical load is on is proportional to energy, not power.
A capacitor resists a change in voltage, proportional to current, and inversely proportional to capacitance. The equation of a capacitor is dv/dt = i/c.
False. The strength of an electrical signal is not directly proportional to its frequency. The strength of an electrical signal is related to its amplitude, which is the height of the signal. Frequency, on the other hand, refers to the number of cycles of the signal that occur in a given unit of time.

Amps Ohm's law states the current is directly proportional to the applied emf (voltage) and inversely proportional to the resistance of the circuit.
In an electrical circuit, current is directly proportional to voltage and inversely proportional to resistance. This relationship is described by Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R), or I V/R.
The electrical resistance of an object is a measure of its opposition to the passage of a steady electric current. An object of uniform cross section will have a resistance proportional to its length and inversely proportional to its cross-sectional area, and proportional to the resistivity of the material.Discovered by Georg Ohm in the late 1820s,[1] electrical resistance shares some conceptual parallels with the mechanical notion of friction. The SI unit of electrical resistance is the ohm, symbol Ω. Resistance's reciprocal quantity is electrical conductance measured in siemens, symbol S.
Electrical forces are inversely proportional to the square of the distance separating the charges.
