Q3. What is current
Ans. 
Current is the flow of electric charge in a circuit.
• Current is measured in amperes (A).

• It is caused by the movement of electrons or other charged particles.

• Current can flow in both directions in an alternating current (AC) circuit.

• In a direct current (DC) circuit, current flows in only one direction.

• The magnitude of current is determined by the voltage and resistance in the circuit.

• Ohm's Law states that current is equa

Q4. What is DC current
Ans. 
DC current stands for Direct Current, which is the flow of electric charge in a single direction.
• DC current is characterized by a constant and steady flow of electrons in one direction.

• It is commonly produced by batteries, solar cells, and power supplies.

• Unlike AC (Alternating Current), DC current does not change its direction periodically.

• DC current is used in various applications such as powering electronic devices, ...read more

Q4. What is the diod
Ans. 
A diode is a semiconductor device that allows current to flow in one direction only.
• Diods are commonly used in electronic circuits to control the direction of current flow.

• They have two terminals - an anode and a cathode.

• When forward biased, a diode allows current to flow. When reverse biased, it blocks current.

• Examples of diodes include light-emitting diodes (LEDs) and rectifier diodes.
