How does the voltage applied to a circuit affect the current flowing through the wire?
Voltage is equal to the Current multiplied by the Resistance.Without changing the resistance, increasing the applied voltage in a circuit will increase current flow. There is a simple, direct relationship between voltage and current. Double the voltage, twice the current will flow. Triple the voltage, and the current will triple. As voltage (E) equals current (I) times resistance (R), when resistance is fixed, what happens to voltage will happen to current.
Ac voltage applied across a load resistance produce alternating current?
The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.
The resistance of a copper conductor will decrease with an increase of applied voltage?
No, the resistance of a copper conductor does not vary according to applied voltage. It is constant for a given wire size, and only varies with temperature. Of course, current through a conductor causes it to heat, so current, not voltage, indirectlycauses a change in resistance.
If the voltage applied to a circuit remains constant and the resistance in the circuit is increased the current will?
V = IR Where, V = voltage I = current R = resistance Thus if resistance is increased with constant voltage current will decrease
Why does higher applied voltage with the same resistance results in more current?
Ohm's law: Voltage = Amperes times Resistance. This means that increasing voltage while keeping resistance the same must result in an increase of current.
What is difference in resistance and reactance?
Resistance is a concept used for DC. the current through a resistance is in phase with the applied voltage Reactance is used for AC the current through a inductive reactance lags the applied voltage by 90 degrees. the current through capacitive reactance leads the applied voltage by 90 degrees. the net reactance is the difference between inductive and capacitive reactance

How to find resistance?
-- Apply a small, known voltage between the terminals of the device. -- Measure the current through the device with the voltage applied. -- Calculate the resistance of the device. It's (voltage) divided by (current).
What are those different power ratings for the same resistance?
The amount of current that will pass through a resistance is dependant upon the voltage applied across the resistance. Voltage devided by resistance equals current. This is Ohm's Law.
Ac voltage applied across a load resistance produce alternating current?
The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.

What does a current in a circuit depend on?
current depends on applied voltage and resistance.
What limits the current that flows through a circuit for a particular appllied DC voltage?
The voltage applied and the resistance across it.
How does current vary with the resistance in the circuit if the voltage is constant?
Inversely. As resistance increases, current dereases; given that the applied voltage is constant.
How much current will flow through a 12 ohm resistor if 6 volts are applied across it?
Voltage / Resistance = Current, you do the math
If the voltage applied to a circuit remains constant and the resistance in the circuit is increased the current will?
V = IR Where, V = voltage I = current R = resistance Thus if resistance is increased with constant voltage current will decrease
What is ac resistance of a diode?
ratio of ac voltage applied across the diode to the ac current flowing through it
