Here are the answers:6. **d. Dioda** A diode is a semiconductor device that allows current to flow in only one direction. It's formed by the junction of P-type and N-type semiconductor materials.7. **c. Cahaya** A Light Dependent Resistor (LDR) changes its resistance based on the amount of light falling on it.8. **a. Capacitor** A capacitor stores electrical energy in an electric field.9. **d. Kapasitas battery** Battery capacity refers to the total amount of electrical charge a battery can deliver at a given discharge rate until its voltage drops to a specified level.10. **c. 1,25** The standard specific gravity of electrolyte in a lead-acid battery at 20°C (not 200°C, which is an error in the question) is approximately 1.25. 200°C is far too high a temperature for a lead-acid battery electrolyte.11. **d. Hydrometer** A hydrometer is used to measure the specific gravity of the electrolyte in a battery.12. **d. Menambah nilai resistansi** Increasing resistance will *reduce* the magnetic field strength. Increasing current, adding turns to the coil, and adding a ferromagnetic core will all increase the magnetic field.13. **b. Trafo** A transformer is used to increase or decrease voltage and current levels in an AC circuit.
