After reading and understanding DC circuits, answer the following problems below: 1. A 20W, 220V bulb is connected in parallel with a 15W, 220V bulb. What is the net resistance? 2. The total resistance is 25KQ and the battery emf is 24V. If the time constant is measured to be 45us, calculate (a) the total capacitance of the circuit and (b) the time it takes for the voltage across the resistor to reach 16V after switch closed. switch 3. Eight identical lights are connected in series across a 220V line. (a) What is the voltage across each bulb? (b) If the current is 050A, what is the resistance of each bulb, and what is the power dissipated in each
