How as the blank applied to a circuit increases the power and the current also increase?
answer is actually voltage
The relationship between resistance and conductors is?
ALL resistance are conductors. just the magnitude value changes
What are the basic principles of ohms law?
Not all circuits obey Ohm's Law; in fact, most don't!Ohm's Law is a law of constant proportionality, and states that 'the current flowing through a conductor is directly-proportional to the potential difference across the ends of that conductor providing physical conditions, such as temperature, remain constant'. Expressed another way, the ratio of voltage to current must be a constant for variations in voltage, for Ohm's Law to apply.Ohm's Law only applies to linear ('ohmic') materials which includes metals, providing their temperatures are constant. Electrolytes, gases, semiconductors, however are non-linear ('non-ohmic'), and Ohm's Law doesn't apply to these.The ratio of voltage to current is resistance, and this applies to all circuits, whether linear or non-linear. But it only tells us what the resistance happens to be at that particular ratio. But for Ohm's Law to apply, the resistance must remain constant for changes in voltage. Put simply, if the resistance of a circuit changes when the applied voltage varies, then it is not obeying Ohm's Law.
Is the resistance of a resistor the same as voltage changes?
Yes and no. As voltage changes, current changes, causing power to change, with the end result that temperature changes. Most resistors have a small temperature coefficient, so their resistance will change slightly as the voltage changes.
How the resistance value for the linear resistance can be changed?
Resistance can be changed by strain over time and changes in the temperature. Resistance thermometers are sensors that are used to measure temperature by correlating the resistance of the RTD elements.
How the current in a circuit changes if the voltage in the circuit is decreased and the resistance remains the same?
If the ratio of voltage to current is constant, then the circuit is obeying Ohm's Law. If the ratio changes for variations in voltage, then the circuit does not obey Ohm's Law.
Is there a relation between capacitance and amps?
q=cv so current changes with change in voltage keeping c constant
What is the trajectory of the projectile?
An "ideal" projectile trajectory ... without the influence of wind or air resistance ... is a section of a parabola. That's the figure you get when the horizontal position changes at constant speed and the vertical position changes at a speed that is itself changing at a constant rate.

What changes as an object moves with a constant acceleration?
During constant acceleration, either the object's speed changes at a constant rate, or the direction of its motion changes at a constant rate, or both.
Name the quantity that essentially changes when a body moves?
A moving body can be broken into the factors of mass and velocity. Momentum is the quantity that changes as velocity increases or decreases, assuming mass is held constant.
What changes with the electric current?
Since V=IR then the answer would be voltage and/or resistance.AnswerIn the equation, V = IR, resistance is a constant -so it does not change with a change in current.
How the current in a circuit changes if the resistance increase and the voltage remains constant?
If the resistance increases, the current diminishes. The voltage may drop a little and the multimeter can't read it or can't accuse so little voltage dropping.
What do you expect of ohmic resistance as you increase or reduce temperature?
It depends. In general, pure metal conductors increase in resistance as their temperature increases; some alloys (e.g. constantan) are manufactured to maintain an approximately-constant resistance for changes in temperature. Materials such as carbon (and most insulators) exhibit a fall in resistance as their temperatures increase.
The resistance of an object to changes in its motion?
The resistance of an object to changes in its motion is known as inertia. Changes in an objects motion include changes in its speed and direction.
In a series circuit when adding light bulbs does the current change?
Yes. The current is inversely proportional to the resistance. I = V / R where I is current, V is voltage, and R is resistance. Adding light bulbs adds resistance. Current is constant throughout a series circuit; it doesn't change no matter what. Voltage changes.
