Diskusi Concepts
1. 🟢 Question 1: What is an electric circuit and what are its basic components? An electric circuit is a closed path facilitating electric current flow. Its primary components are: Battery: The source supplying necessary voltage. Resistor: Component that regulates current flow to safeguard others. Conductive Wires: Materials allowing current passage among components. 2. 🟢 Question 2: How can we use Ohm's Law to find the current in a circuit with a resistance of 10 ohms and a voltage of 5 volts? According to Ohm's Law, V = I x R, where V represents voltage, I represents current, and R is resistance. To find the current, rearrange to I = V / R. Here, I = 5 volts / 10 ohms = 0.5 amperes. 3. 🟢 Question 3: Describe the journey of electric current in a simple circuit with a battery, resistor, and conductive wires. The current flows from the positive end of the battery through the wires to the resistor, where some energy gets converted to heat. It then continues back through the wires to the battery's negative end, completing the circuit.
