Suppose that the cost of electrical energy is $0.12 per kilowatt hour and that your electrical bill for 30 days is $60. Assume that the power delivered is constant over the entire 30 days. What is the power in watts? If this power is supplied by a voltage of 120 V, what current flows? Part of your electrical load is a 60 W light that is on continuously. By what percentage can your energy consumption be reduced by turning this light off?

Q1) What is current in terms of charge?
a) Current is measured 2A in a DC circuit
* How much charge is involved in the process?
* How many electrons are involved in the process?
* The voltage source of this current is 12 Volts. What is the power produced by the source?
1. Discuss your observations on both series and parallel circuit. (Brightness of light bulb)
2. Briefly discuss the differences of series and parallel circuit based on current, voltage, and resistance.
3. Do batteries last longer in series or parallel?
4. What is Electricity?

7. A 100 W incandescent lamp has a resistance when cold (lamp extinguished) that
is only 1/12 of its hot (lamp illuminated) resistance value.
a) What is the lamp current and its hot resistance when placed across a 120 V
line?
b) What is the cold resistance of this lamp?
c) What is the instantaneous current through the lamp at the moment it is
switched on?
d) What power does the lamp dissipate at this instant?
