A 100W, 120V lightbulb and a 60W, 120V lightbulb are connected in two different ways. In each case, which bulb glows more brightly? Ignore change of filament resistance with current and temperature. Explain your answer. 60W 100W 60W 100W Activity 2: Solve the following problems. Show your solutions neatly. 1. How many 10 Q resistors must be connected in series to give an equivalent resistance to five 100 Q resistors connected in parallel? 2. A 650 0 and an 1800 0 resistor are connected in series with a 12 V battery. What is the voltage across the 1800 Q resistor? 3. Three 45 0 lightbulbs and three 65 ( Lightbulbs are connected in series a.) What is the total resistance of the circuit? b.) What is the total resistance if all six are wired in parallel?Resistors are connected in parallel and series as shown in the circuils below. Find the 3.] equivalent resistance of the combined resistors h.) Current flowing through each resistor no} voltage drop across each resistor and d.) the power dissipated by each resistor. e.II Find the pawn output of the smrce. 1|l
