Understanding Electricity Concepts

I = V + R

V = I * R

R = V - I

V = R / I

ohms

watts

volts

amps

Resistor, capacitor, transformer

Battery, switch, diode

Power source, load, conductive pathways

Generator, inverter, relay

The function of a resistor in a circuit is to limit current and control voltage.

To increase current flow in a circuit.

To convert electrical energy into heat.

To store electrical energy for later use.

P = V + I

P = I / V

P = V - I

P = V × I

The total resistance is greater than the individual resistances.

The total resistance is less than the smallest individual resistance.

The total resistance is equal to the individual resistances.

The total resistance is the average of the individual resistances.

The total current remains constant regardless of branches.

The total current is only determined by the largest branch.

The total current decreases as more branches are added.

The total current increases as more branches are added.

Electromagnetism is the study of sound waves.

Electromagnetism refers to the force between two solid objects.

Electromagnetism is the process of generating electricity from heat.

Electromagnetism is the interaction between electric charges and magnetic fields.

A capacitor converts electrical energy into heat.

A capacitor acts as a resistor in a circuit.

A capacitor stores and releases electrical energy in a circuit.

A capacitor amplifies electrical signals in a circuit.
