Since Ohm's law states that current is voltage divided by resistance, if you place 240 volts across 10 ohms, you will get 24 amperes. This is true for AC and DC. It is also true for inductive or capacitive circuits, except that the calculation of apparent resistance (reactance) and phase angle of current to voltage becomes more complex.

When an alternating voltage is applied to purely resistive circuit what happens?
When an alternating voltage is applied to a purely resistive circuit, the resulting current is in phase with the voltage.
The resistor in an R-L series circuit has a voltage drop of 53V and the inductor has a voltage drop of 28V what is the applied voltage of the circuit?
The applied voltage is 53+28 = 81V.
When you short out a resistor in a parallel circuit why does the current lower?
The total resistance of a set of resistors in parallel is found by adding up the reciprocals of the resistance values, and then taking the reciprocal of the total. By removing a resistor the total current will lower. If you short out the parallel circuit as suggested it will take out the fuse that should be protecting the circuit.AnswerShorting-out a resistor in a parallel circuit, will act to short out the entire circuit, therefore, significantly increasing, not lowering, the current! And, as the previous answer indicates, this short-circuit current will operate any protective devices, such as a fuse.In a parallel circuit current does not lower but it will be increase if shorting-out one resistor in the two resistor parallel circuit, the circuit will become very low resistive and the larger current will flow through the short path.
What are the effects of power on a resistive device?
Current passing through a resistor, et al, causes heat. The heat causes the resistance of said resistor to decrease, which causes current to increase, and the cycle just keeps going until the circuit burns out.
What is the power developed in a purely resistive circuit with 15volts rms applied and drawing 10 amps?
(15 volts) x (10 Amps) = 150 watts
When an alternating voltage is applied to purely resistive circuit what happens?
When an alternating voltage is applied to a purely resistive circuit, the resulting current is in phase with the voltage.
What is the applied voltage to a resistive capacitive circuit?
this is the amount of voltage a circuit can hold.
What is a purely resistive circuit?
It does not contain unidirectional outputAnswerA purely resistive circuit is an 'ideal' circuit that contains resistance, but not inductance or capacitance.
What is the relationship between resistance and current in a resistive circuit?
:) It's connected together
What does a resistor do to the flow of energy?
It depends on what sort of circuit the resistor(s) is in. The resistor(s) can lower either EMT (Voltage) or Current (Amperage) Sometime resistors are used to create an EMT differential whenever current is flowing.
The resistor in an R-L series circuit has a voltage drop of 53V and the inductor has a voltage drop of 28V what is the applied voltage of the circuit?
The applied voltage is 53+28 = 81V.
How do you determine if the Primary voltage is unknown but Secondary voltage is given?
If a secondary voltage is given across a particular resistive load in a series of known resistive loads, multiply the voltage by the ratio of the total load to the measures load to get total voltage. Example: You have a series of a 200 ohm resistor to a 100 ohm resistor. The votage measured across the 100 ohm is 2 volts. 200 + 100 = 300. 300 / 100 = 3. 2 X 3 = 6. Total Voltage in the circuit is 6V
What is driven RL circuit?
A driven RL circuit is a circuit that contains a resistor (R) and an inductor (L) connected in series with an external source of alternating current (AC) or voltage. The external source provides energy to the circuit, driving the current through the inductor and resistor. This circuit can exhibit interesting behavior such as resonance and phase shifts due to the interplay between the inductive and resistive components.
What is power factor of resistor?
A resistor doesn't have a power factor. However, if a circuit is pure resistance in nature the power factor will be one when a voltage is applied and a current flows in the circuit. The power factor is a measure of the relative phases of the current and voltage in a circuit.
The power factor of a purely resistive circuit will be?
The power factor of a purely resistive circuit is 1.0.

The current I though all resistor is the same?
If you have one or more resistive elements in a circuit connected in series, the current through them will be the same.To make it easier to understand, think of the resistors as being bottlenecks in the circuit for the flow of electrons. The speed at which the electrons move in the circuit (aka - the current) is limited by the narrowest bottleneck. In this case, the narrowest bottleneck represents the most resistive element.
