PLEASE SHOW WORK SO I CAN UNDERSTAND!200 C of charge flows for 45 seconds. Calculate the electric current (in amps).


1.200 C of charge flows for 45 seconds. Calculate the electric current (in amps).

2. A current of 10 A flows through an appliance connected to a standard 120 volt outlet. Calculate the resistance (in ohms) of the appliance.

3.Calculate the voltage (in volts) needed to cause a current of 0.002 A to flow through a 10,000 ohm resistor.

4.. Calculate the power consumption (in watts) of a 2,000 A train motor that operates on 800 volts.

5.Calculate the energy in joules used by a 3,500 W appliance that is operated for 30 minutes.

6. Calculate the cost (in cents) of using a 200 watt television for 30 days if turned on 2 hours per day and if electricity costs 10 cents per kilowatt-hour .

7.A car battery is rated at 600 AH (i.e., amps x hours). Calculate the number of coulombs this is equivalent to

8.A flashlight bulb uses 6 watts at a voltage of 12 volts. Calculate the current (in amps) used by the bulb.

9.Calculate the voltage (in volts) needed to supply 2 amps through a resistance of 6 ohms.
