Electricity and Circuits Vocabulary regular flashcards

Flashcards covering key vocabulary terms and concepts from the lecture notes on current, voltage, electric shock, circuits, and Ohm's Law.

Current (I)

The amount of charge flowing through a wire per unit time.

Voltage (U)

The energy provided or used per unit of electric charge.

Electric Current

Flow of electrons.

Voltage

Driving energy that pushes the current.

Ammeter

Measures current in series

Voltmeter

Measures voltage in parallel

10 mA

Can cause muscle paralysis.

75+ mA

Can cause ventricular fibrillation.

1 A

Likely fatal effects.

Series Circuits (Current)

Same current flows through all components.

Series Circuits (Voltage)

Voltage splits among components.

Series Circuits (Resistance)

Total resistance adds up.

Parallel Circuits (Voltage)

All components share the same voltage.

Parallel Circuits (Current)

Total current splits into branches.

Parallel Circuits (Resistance)

Total resistance decreases with more paths.

Series Circuits

One single path

Parallel Circuits

Multiple paths

Ohm's Law

The voltage across a resistor is proportional to the current times the resistance.

Resistivity

Longer and thinner wires have more resistance; material matters.

Resistance

Measure of how much a component resists current.
