Ley de Ohm y Ley de Watt

What is the formula for Ohm's Law?

• I = V x R

• I = V / R

• I = R / V

• I = V + R

How do you calculate resistance in a circuit?

• R = V - I

• R = I / V

• R = V / I

• R = V x I

What is the formula for power calculation in a circuit?

• P = V ^ I

• P = V * I

• P = V / I

• P = V + I

How is current measured in a circuit?

• Counting the number of electrons passing through the circuit

• Measuring the temperature of the circuit components

• Using an ammeter connected in series with the circuit

• Using a voltmeter connected in parallel with the circuit

What is the difference between series and parallel circuits?

• The color of the wires used

• The size of the components

• The temperature at which they operate

• The main difference between series and parallel circuits is how components are connected and how current flows through them.

If a circuit has a voltage of 12V and a current of 2A, what is the resistance?

If a circuit has a resistance of 10 ohms and a current of 5A, what is the power?

• 250 watts

• 100 watts

• 150 watts

• 50 watts

In a series circuit, how does the total resistance compare to individual resistances?

• Total resistance is greater than the sum of individual resistances.

• Total resistance is equal to the sum of individual resistances.

• Total resistance is less than the sum of individual resistances.

• Total resistance is unrelated to individual resistances.

In a parallel circuit, how does the total current compare to individual branch currents?

• The total current is equal to the sum of the individual branch currents.

• The total current is greater than the sum of the individual branch currents.

• The total current is less than the sum of the individual branch currents.

• The total current is unrelated to the individual branch currents.

What happens to the total resistance in a parallel circuit as more branches are added?

• Total resistance decreases

• Total resistance increases

• Total resistance remains the same

• Total resistance becomes infinite
