What is the difference between AC GND,and DC GND. Although there can be times in power circuits where AC ground is separate from DC ground, you are probably confusing the terms with AC-grounded and DC-grounded. If a circuit is grounded through a capacitor it is referred to as AC-grounded...
Q1. Explain the difference between kVA and kW? Ans: In kVA: Both kinds of power are equal in DC circuits and only a fraction of kVA is accessed to do work and the rest is considered as excess in the current. In kW: Both kinds of power are different in AC circuits. It shows us t...
For the newcomers in the field of electronic the following note will prove quite useful, lets learn exactly what;s the difference between alternating and direct current or simply AC and DC. As the name refers to an alternating current is a current which alternates or fluctuates between a certai...
The difference betweenAlternating Current (AC)andDirect Current (DC)is simple: AC vs DC comes down to how the current flows. AC is a current that alternates its direction. It goes back and forth continuously. DC is a current that flows in one direction. Current flow in a DC circuit: For...
Early recognition of trouble in mains=connected inverters - comparing absolute DC and difference between DC and AC side currents with permissible limitsA subsynchronous inverter cascade is constituted by an induction motor (M) with starting resistance (R), power switches (Q), a bridge rectifier (...
Power delivered from a Direct Current source is known as DC power. Voltage and the current across a circuit or a component do not vary under stable conditions in a DC power system. Therefore, the time rate of energy delivered by the source remains unchanged. The relation between the direct ...
Now that we’ve covered how direct current voltage is produced, how does DC voltage actually work to power electronics and devices? In any DC circuit, the power source maintains a constant electric potential difference between two points, denoted as positive and negative. This results in an elec...

(C ) Write the frequency of AC and DC. View Solution A capacitor only is connected to an AC source. What will be the phase difference between the current flowing in the circuit and the potential difference between the plates of the capacitor? View Solution What is a phasor ? What is...
You can use diodes such as the Zener diode in converting between alternating current (AC) and direct current (DC). AC current changes between flowing in one direction and flowing in the other while DC current only moves in one direction. You can find bridge rectifiers, or rectifier diodes, ...
