What is power in a simple 12 volt 4 amp dc series circuit?
Power in a circuit can be calculated using the formula ( P = V \times I ), where ( P ) is power in watts, ( V ) is voltage in volts, and ( I ) is current in amps. In a 12-volt, 4-amp DC series circuit, the power would be ( P = 12 , \text{V} \times 4 , \text{A} = 48 , \text{W} ). Therefore, the power consumed in this circuit is 48 watts.
How dc power is converted into ac power in inverter?
Dc is used to power an oscillator circuit of which the frequency can be controlled such as 60 HZ.
What is the direction of DC current flow in a circuit?
In a circuit, DC current flows from the positive terminal of the power source to the negative terminal.
Why DC-DC converter is used in telecommunication power supply instead of inverter?
DC-DC conversion offers the advantage of a bifurcated power source. AC can be rectified and filtered to supply power under normal conditions at say, 17VDC fed to a 9VDC regulator to power the circuit. A 12VDC battery can serve as an alternate feed to the circuit for times when the AC source fails -- and it is connected to the same 9VDC regulator. Another benefit of DC-DC conversion is isolation to the circuit from noisy events.
When DC power is first applied to an uncharged capacitor it appears as a?
When DC power is first applied to an uncharged capacitor it appears as a short circuit.
How do you filter DC power?
D.C power can be filtered using low pass capacitive circuit
How do you conver ac power into pulsating DC What devices you need?
rectifier circuit convert ac to dc signal
What is the var meter?
A VAR Meter is used to measure Reactive Power in AC Circuits - Pure reactive components dissipate zero power, which makes sense in a DC circuit, as a capacitor passes no DC current and an inductor displaces no voltage. Yet, in an AC circuit, the reactive components "seem" to dissipate power, as current passes through the capacitor and the inductor sees a voltage drop. This counterfeit power is called "reactive power" and is measured not in Watts, but in VARs (Volt-Amps-Reactive). Its mathematical formula symbol is "Q".

A circuit carrying current in one direction is called a?
A circuit carrying current in one direction is called a direct current (DC) circuit. In a DC circuit, the flow of electric charge is constant and does not change direction. This is in contrast to an alternating current (AC) circuit, where the flow of electric charge changes direction periodically. DC circuits are commonly used in electronics and power transmission systems.
How can a radio use both DC and AC?
Radios use DC power supplies to operate. If a radio is powered from a mains AC supply, a power supply circuit will convert the AC supply to DC. Therefore, a radio may have both a DC and an AC power input but ultimately, the internal circuitry will always use DC.
