I, R + V

• Current = movement of electrons
• Voltage = pushing force
• Resistance = stopping force (if stopping force is too high, current stops)
• Think of current as the flow of a waterfall and the voltage the force of the waterfall
• pushing force = voltage
• stopping force = resistance
• movement of electrons = current
• increased voltage = increased current (goes faster)
• more current = more electrons pass a point
• Current is measured in Amps
• Resistance is measured in ohms (Ω)
• Voltage is measured in volts (V)
• Voltmeter = measures voltage in parallel with circuit (extra loop)
• Ammeter = measures current in series
• in equations, current = I
• Lower current = more resistance
