Electricity Concepts and Terminology Flashcard

Front

What is the formula to calculate current (I) in a circuit?

Back

I = V / R, where I is current in Amps, V is voltage in Volts, and R is resistance in Ohms.

Front

What is resistance in the context of electricity?

Back

Resistance is the opposition to the flow of electric charges in a material, measured in Ohms.

Front

What is the unit of measurement for electric current?

Back

The unit of measurement for electric current is Amperes (Amps).

Front

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

Back

According to Ohm's Law, voltage (V) is equal to the current (I) multiplied by the resistance (R): V = I * R.

Front

If a circuit has a voltage of 12V and a resistance of 6Ω, what is the current?

Back

2 Amps.

Front

What is the flow of electric charge called?

Back

Electricity.

Front

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

Back

The current decreases.

Front

What is the formula to calculate voltage (V) in a circuit?

Back

V = I * R, where V is voltage in Volts, I is current in Amps, and R is resistance in Ohms.

Front

If the current in a circuit is 4 Amps and the resistance is 2 Ohms, what is the voltage?

Back

8 Volts.

Front

What is the formula to calculate resistance (R) in a circuit?

Back

R = V / I, where R is resistance in Ohms, V is voltage in Volts, and I is current in Amps.
