Electric Circuits & Electricity0p

Current

• Voltage is an electrical push

• Electrons come for the (-) end

• Will only occur from electrical potential difference, meaning there is a potential difference from one end of a battery to another.

Ohm’s Law

• states about the interrelationship between voltage, current, and resistance

• resistor - an electronic component that resists the flow of a current in a circuit (eg, light bulb)

Ohm’s Law and Electric Circuits

• When bulbs aren’t connected together, the amps would be the same all throughout because there’s no resistance

• In circuits where bulbs are connected together, this creates resistance, therefore there will be lower amps.

Circuits - Series and Parallel

• Series Connections: Electric current travels down a single path

  • if one breaks, others after won’t work

• Parallel Connections: Electrical current can travel down more than one available path.

  • will not affect other bulbs if one breaks
