What is the relationship between voltage and frequency in an electrical circuit?
In an electrical circuit, the relationship between voltage and frequency is that they are independent of each other. Voltage refers to the electrical potential difference between two points in a circuit, measured in volts. Frequency, on the other hand, refers to the number of cycles per second of an alternating current, measured in hertz. While voltage can affect the power of an electrical circuit, frequency determines the speed at which the current alternates direction.
What is the effective voltage of the electrical circuit?
The effective voltage of an electrical circuit is the measure of the average voltage over a complete cycle of alternating current. It is also known as the root mean square (RMS) voltage.
If you multiply the voltage in a circuit by the current what are you going to get for your answer?
You would get the power in the circuit, which is measured in watts (W). The formula for power is P = V x I, where P is power, V is voltage, and I is current.
What does AC and DC stand for in the electrical field?
Alternating Current and Direct Current. Electricity is voltage and current. Voltage is electrical pressure, and current is the flow of charged particles. The difference between alternating current (AC) and direct current (DC) is that the electrons in an AC circuit regularly reverse their direction. In a DC circuit electrons always flow in the same direction.
How does changing the voltage in a circuit affect the current in the circuit?
Changing the voltage in a circuit will alter the current flowing through it. According to Ohm's Law, the current is directly proportional to the voltage in the circuit. Increasing the voltage will lead to an increase in current, and vice versa.
What is Alternating current is measured in?
Alternating Current is measured in Amperes.
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 an opposition to current flow called that occurs in an alternating current circuit?
The resistance is called impedance, and is equal to the measured voltage divided by the measured current, through Ohm's Law (V = ZI, Z = V/I).
What is it mean to say that an alternating current leads or lags an alternating emf?
It is another way of saying that the circuit is capacitive reactive circuit. Look up the mnemonic ELI the ICE man. ELI, voltage leads the current in an inductive circuit. ICE, current leads the voltage in a capacitive circuit.

Why during measurement the measured voltage and currents have negative sign?
Because of the polarity of the circuit. The signs of measured current and voltage depends on the direction of the current and voltage.
What is term used when an Alternating current acts like a direct current?
Perhaps you are asking how the voltage of alternating current is measured, to be equivalent to the voltage of a direct current system. Alternating current and direct current have distinct properties. With direct current, voltage is at a constant polarity, and a direct current voltage source will maintain a uniform, constant voltage level. Alternating current reverses polarity at a given frequency and therefore it's voltage continuously varies from a positive peak voltage level, through zero, to a negative peak voltage level, repeating this cycle continuously. For this reason, voltage of an alternating current system, is measured in root-mean-square (rms), which is a voltage, which when multiplied by the current in amperes, calculates power which is equivalent to that of direct current of the same voltage and current values. With a typical sinusoidal waveform, the peak voltage of alternating current is divided by the square root of 2 to determine the rms voltage. The 120 volts output in the wall outlet in our home is actually about 170 peak volts.

What is the science behind the alternating current?
When a sinusoidal alternating voltage is applied in a circuit, the resulting alternating current is also sinusoidal and has the same frequency as that of applied voltage .However, there is generally a phase difference between the applied voltage and the resulting current.This is how alternating-current circuit works.
