This week of the Ron Paul physics course focused primarily on DC circuits. Lots of diagrams were drawn out and practice problems were given.
Lesson 1:
- Capacitors in parallel
- Capacitors in series
Lesson 2:
- Charging a capacitor
When the switch of a circuit closes the capacitor begins to charge.
- RC time constant
The product of the resistance and capacitance is called the time constant.
Lesson 3:
- RC circuit applications
- Flashing lights
- Pacemakers
- Effective resistance of the body
Ohms laws still apply. If the body has a high effective resistance and comes in contact with a voltage source, they will experience a small current. If they have a low resistance, they will experience a large current.
Whether a person is wet or dry or grounded will affect the persons resistance.

Lesson 4:
- Voltmeter
Used to measure volts
- Ammeter
Used to measure current
