1. There is a constant current of 5 A in a wire for 10.0
min.
a) How much total charge passes a given point in the circuit
during those 10.0 min?
b) How many electrons would that be?
c) If the load were 500 C, then how much current passes through
the circuit during 10.3 min?
2. Calculate the resistance of the headlights of a 200 W
airplane designed for 60 V.
3. If the resistance of the headlights of a car were 7.2 Ω,
then, Calculate the energy power (in watts) if the lanterns were
designed for 20 V?
4. An electric heater draws a constant 15.0 A on a 120 V line.
How much power required and how much does it cost per month (31
days) if you operate 3.0 hrs per day and the electric company
charges 21.2 cents per kWh?
