Diskusi Concepts

1. 🛑 Question 1: What is an electric circuit and what are its basic components? An electric circuit is a closed path that allows electric current to flow. The fundamental components of a circuit consist of: Battery: A power source providing the required voltage for current flow. Resistor: A component limiting the current passing through the circuit, safeguarding others. Conductive Wires: Materials enabling current to flow between the circuit components. 2. 🛑 Question 2: How can Ohm's Law be used to determine the current in a circuit with a resistance of 10 ohms and a voltage of 5 volts? Ohm's Law states that V = I x R, where V is voltage, I is current, and R is resistance. To find the current, rearrange the formula to I = V / R. Here, the current would be I = 5 volts / 10 ohms = 0.5 amperes. 3. 🛑 Question 3: Describe the journey that electric current makes in a simple circuit that has a battery, a resistor, and conductive wires. The electric current flows from the positive terminal of the battery, through the conductive wires to the resistor, where some energy dissipates as heat. Then, it continues through the wires back to the battery's negative terminal, completing the circuit.
