Dc Circuit Flashcards
What is Ohm’s Law?
Ohm’s Law states that the current in a circuit is directly proportional to the voltage and inversely proportional to the resistance.
What is the formula for Ohm’s Law?
V = IR, where V is voltage, I is current, and R is resistance.
What happens to current if resistance in a circuit is increased?
If resistance is increased, the current in the circuit decreases.
What happens to current if voltage in a circuit is doubled?
If voltage is doubled, the current in the circuit doubles as well.
What happens to potential difference if resistance in a circuit is doubled?
If resistance is doubled, the potential difference across the circuit is also doubled.
What is the relationship between current, resistance, and potential difference in a series circuit?
In a series circuit, the total resistance is the sum of individual resistances, and the current is the same through all components.
What is the relationship between current, resistance, and potential difference in a parallel circuit?
In a parallel circuit, the total current is the sum of currents through individual branches, and the potential difference is the same across all branches.
What is the power dissipated in a circuit?
Power dissipated in a circuit is the rate at which energy is transferred by an electric circuit.
What is the formula for power in an electric circuit?
P = VI, where P is power, V is voltage, and I is current.
What is the relationship between energy, power, and time in an electric circuit?
Energy can be calculated as the product of power and time, E = Pt.
