Q:Explain the difference between AC and DC currents.A: AC (Alternating Current) and DC (Direct Current) are two types of electrical current. AC changes direction periodically, while DC flows in one constant direction. AC is commonly used in power supply systems due to its ease of transformation into different voltages, whereas DC is often used in battery-powered or electronic devices.... Read More »
Q:Define Kirchhoff’s laws.A: Kirchhoff’s laws consist of two rules essential in circuit analysis. Kirchhoff's Current Law (KCL) states that the total current entering a junction equals the total current leaving it. Kirchhoff's Voltage Law (KVL) says that the sum of all electrical voltages around a loop is zeroQ:What are the types of electrical circuits?A: Electrical circuits can be classified into series,...

Q: What is the role of a diode in an electrical circuit?Answer: diode is a semiconductor device that allows current to flow in one direction only. It acts as a one-way valve, permitting the passage of electric current when the voltage across it is in the forward direction. Diodes are crucial in rectification, signal demodulation, and electronic protection.Q:Describe a capacitor and... Read More »
