What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (E) across the two points and inversely proportional to the resistance (R) of the conductor. It is expressed as E = I * R.

Front

What happens to the current in a series circuit?

Back

In a series circuit, the current remains the same throughout all components.

Front

What is electricity?

Back

Electricity is the flow of electrons from atom to atom.

Front

What happens to the total circuit current when a resistor in a series circuit is replaced with one of higher resistance?

Back

The total circuit current will decrease.

Front

What is the relationship between total resistance and individual resistances in a parallel circuit?

Back

In a parallel circuit, the total resistance is less than the lowest individual resistance.

Front

Define voltage.

Back

Voltage (E) is the electric potential difference between two points in a circuit, measured in volts (V).

Front

Define amperage.

Back

Amperage (I) is the measure of the flow of electric charge in a circuit, measured in amperes (A).

Front

Define resistance.

Back

Resistance (R) is the opposition to the flow of electric current, measured in ohms (Ω).

Front

What is Kirchhoff's Law?

Back

Kirchhoff's Law states that the total current entering a junction must equal the total current leaving the junction.

Front

What is a series circuit?

Back

A series circuit is a circuit in which components are connected end-to-end, so that the current flows through each component in turn.
