When a load is connected, does the output voltage decrease? What happens to the total resistance when a fourth resistor is connected in a series with three resistors? How can I represent a schematic diagram of circuit for three D-cells placed in a battery pack to power a circuit containing three light bulbs in series? How can I represent a schematic diagram of circuit for three D-cells placed in a battery pack to power a circuit containing three light bulbs in parallel? When is better to use parallel circuits? What is the equivalent resistance of three resistances of 12 Ω each connected in parallel? What does series circuits mean? What does the last color band represent on a color-coded resistor?

Why is the Thevenin's theorem important for circuit diagrams? Question #ec4ec If all you have is a 120-V line, would it be possible to light several 6-V lamps without burning them out? How? Suppose you connect a battery to a small light bulb with a single wire. What will happen? What is the correct way of connecting an ammeter and a voltmeter? Question #e4173 Question #13465 Given a circuit with resistors R1 = 10 W, R2 = 15 W, R3 = 20 and voltage, #V_b = 12V#, see figure, find the currents through all the resistors? The circuit in the figure has been in position a for a long time, then the switch is thrown to position b. With #Vb = 12 V, C = 10 mF, R = 20 W#. a.) What is the current through the resistor before/after the switch? b) capacitor before/after c) at t=3sec? Initially switch is open, no charge on the capacitor, (a) Close the switch, find #I_i, (i = 1, 2, 3) Q, & V_C# immediately after. (b) Switch is closed for long find #I_i, Q & V_C#. (c) Find #I_i, Q, & V_c# immediately reopened? d) Reopened for long? How do you solve for the voltages and currents in this circuit diagram?
