5G Ohm's - Physics

Front

What is a conductor?

Back

A conductor is a material that allows the flow of electrons.

Front

What is an insulator?

Back

An insulator is a material that inhibits the flow of electrons.

Front

What is a circuit?

Back

A circuit is a closed loop that allows for current to flow continuously.

Front

What is the unit of measurement for current?

Back

The unit used to measure current is Amps.

Front

How do you calculate current in a circuit with a known voltage and resistance?

Back

Current (I) can be calculated using Ohm's Law: I = V/R, where V is voltage and R is resistance.

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 and inversely proportional to the resistance of the conductor.

Front

What is the formula for calculating resistance?

Back

Resistance (R) can be calculated using the formula R = V/I, where V is voltage and I is current.

Front

What happens to current if resistance increases while voltage remains constant?

Back

If resistance increases while voltage remains constant, the current will decrease.

Front

What is the relationship between voltage, current, and resistance in a circuit?

Back

The relationship is defined by Ohm's Law: V = I * R.

Front

What is the effect of connecting resistors in series?

Back

When resistors are connected in series, the total resistance increases and is equal to the sum of the individual resistances.
