What is the difference between external data bus and internal data bus?
A data bus connects different parts of a circuit and comprises a group of parallel wires, each one carrying a different logic signal.
What is the unit of measurement of internal resistance?
unit of internal resistasnce is ohms too. V = I(R+r) V voltage across the circuit I current in the circuit R external resistance r internal resistance unit of internal resistasnce is ohms too. V = I(R+r) V voltage across the circuit I current in the circuit R external resistance r internal resistance
What is the difference between series and parralal circuit?
difference between series is one pathway through circuit,difference between parralal is more then one pathway through circuit.
What is the difference between mlln and data circuit?
a mlln circuit is a data circuit
Why potential difference across open circuit is more than in closed circuit?
In a closed circuit there is a potential drop due to resistance of wires and battery (internal).AnswerWhen the circuit is closed, the resulting current not only flows through the external circuit, but through the source (battery, generator, transformer, etc.) itself. All sources have an internal resistance, which causes an internal voltage drop, slightly reducing the voltage across the terminals. The larger the current, the larger the internal voltage drop, and the lower the terminal voltage.When the circuit is open, no current flows. So there is no internal voltage drop, and the full voltage appears across the source's terminals.The 'open-circuit voltage' is actually the electromotive force provided by the source.
What is the difference between fuse and MCB?
what is the difference between miniature circuit breaker and fuse
When does Internal resistance equals external resistance?
Internal resistance equals external resistance when the load connected to a battery consumes power equal to that dissipated in the battery's internal resistance. This occurs when the open circuit voltage of the battery drops to zero.
What is difference between magnetic circuit and electric circuit?
magnetic circit has a magnet and electri circuit has electricity
What is the difference between ac and dc generators?
AC generator, the brushes run on slip rings which maintain a constant connection between the rotating coil and the external circuit. This means that as the induced emf changes polarity with every half-turn of the coil, the voltage in the external circuit varies like a sine wave and the current alternates direction. DC generator, the brushes run on a split-ring commutator which reverses the connection between the coil and the external circuit for every half-turn of the coil. This means that as the induced emf changes polarity with every half-turn of the coil, the voltage in the external circuit fluctuates between zero and a maximum while the current flows in one constant direction
Why terminal potential difference is decrease when current in the circuit is increased?
The terminal potential difference decreases when the current in the circuit is increased due to the internal resistance of the power source. As the current increases, the voltage drop across the internal resistance also increases, leading to a decrease in the terminal potential difference available to the external circuit. This is described by Ohm's Law, V = E - Ir, where V is the terminal potential difference, E is the electromotive force of the source, I is the current, and r is the internal resistance.
What is the relationship between voltage and potential difference in an electrical circuit?
Voltage and potential difference are essentially the same thing in an electrical circuit. Voltage is the measure of potential difference between two points in a circuit. In other words, voltage is the force that pushes electric charges through a circuit, and potential difference is the measure of this force.
Can there be a potential difference between two conductors that carry like charges of the same magnitude?
Yes, there can be a potential difference between two conductors that carry like charges of the same magnitude. This can occur if the conductors are at different potentials due to external influences or if the conductors are part of a circuit where there is a potential difference applied.
