What is resistance?, A force that opposes the flow of electric current, A source of battery, A type of battery, A type of wire, What is the unit used to measure resistance?, Volt (V), Ampere (A), Ohm (Ω), Watt (W), Which formula represents Ohm’s Law for finding resistance?, R = V ÷ I, R = V × I, R = I ÷ V, R = V + I, What does a resistor do in a circuit?, Controls or limits electric current, Produces sunlight, Stores food, Makes sound, Which resistor has a constant resistance?, Fixed resistor, Variable resistor, Thermistor, LDR, Which type of resistor can be adjusted?, Fixed resistor, Variable resistor, Special resistor, Diode, In a parallel circuit, what is the same across the branches?, Voltage, Resistance, Current, Wire length, A student connects two resistors in series: 2 Ω and 3 Ω. What is the total resistance?, 1 Ω, 5 Ω, 6 Ω, 9 Ω, Ana notices that a lamp becomes too bright because too much current is flowing. Which component can help control the current?, Resistor, Battery only, Switch only, Wire only, A fan has a control that allows you to make the fan faster or slower. What type of resistor is most related to this function?, Fixed resistor, Variable resistor, LDR, Diode, A light automatically turns on when a room becomes dark. Which special resistor is most useful for this system?, Thermistor, LDR, Fixed resistor, Diode, Two resistors are connected in parallel. If one branch stops working, why can the other branch still work?, Each branch provides a separate path for current., The resistors are no longer needed., The battery becomes stronger., Resistance disappears., A temperature-sensing device changes its resistance when the temperature changes. Which component should be used?, LDR, Diode, Thermistor, Fixed resistor, A circuit has a voltage of 12 V and a resistance of 4 Ω. Using Ohm’s Law, what is the current?, 2 A, 3 A, 8 A, 16 A, Maria wants to design a simple automatic light that turns on when it gets dark. Which combination is the BEST choice?, LDR + circuit, Thermistor + heater, Diode + thermometer, Fixed resistor + fan
