Electric Current and Ohms Law

Front

What happens to the current in a circuit if the resistance increases but the voltage stays the same?

Back

The current would decrease.

Front

What is a flow of electric charge that regularly reverses its direction?

Back

Alternating current.

Front

What is the opposition to the flow of charges in a material?

Back

Resistance.

Front

What happens to the current in a circuit if the voltage is increased?

Back

The current would increase.

Front

What is a charge that flows only in one direction?

Back

Direct current.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

Front

What is the unit of electric current?

Back

Ampere (A).

Front

What is the unit of resistance?

Back

Ohm (Ω).

Front

What is the unit of voltage?

Back

Volt (V).

Front

What is the relationship between voltage, current, and resistance?

Back

V = I × R, where V is voltage, I is current, and R is resistance.
