mica‚ fiberglass and air are good insulators. • Electromotive Force (EMF) is the force that moves electrons through conductors. Its unit of measure is the Volt. Think of it as pressure. • Voltage Source - has two terminals (+ and -). Some examples are car batteries (12 volts DC)‚ D cell batteries (1.5 volts DC) and a wall socket (120 volts AC). • Current - is the flow of electrons. It is measured in amperes. • Resistance (ohms‚ Ω) is the ability to oppose an electrical current. PHYS 401 Physics
