What else can I help you with?
What would the current flow be if a short circuit is put across the battery's terminals?
That will depend on the internal resistance of the battery. I = E / R Where I is the current, E is the open circuit battery voltage, and R is the internal resistance of the battery.
How is a series circuit different to a parell circuit?
The difference between a series and parallel circuit is that a series circuit is connected in such a way that the same current intensity flows through the elements while a parallel circuit is connected in such a way that the same potential appears across their terminals.
Why always voltmeter is connected in parallel with load terminals?
A voltmeter is connected in parallel with load terminals because it is designed to measure the voltage across those terminals without significantly affecting the circuit. When connected in parallel, it can accurately capture the potential difference across the load while maintaining its high internal resistance, which minimizes the current drawn from the circuit. This ensures that the measurement reflects the actual voltage present across the load, allowing for precise voltage readings.
What happens in a circuit to voltage when current flows?
A: There is a relationship one needs the other both can coexists but not each alone.
What is the formula for total current in a series circuit?
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
What is the current source replaced by open circuit across the terminals?
because an ideal current source is assumed to produce a constant current for any voltage and is assumed to have an impedence of infinity (open circuit).
What is the definition to convention current?
Convention current refers to the direction of electron flow in a circuit, from positive to negative terminals. This convention is used for the sake of consistency across circuit diagrams and calculations in physics and electrical engineering.
How does voltage produce current?
Voltage across two terminals mean there exists a potential difference, and when the circuit gets closed, due to this potential difference the current flow.
What would the current flow be if a short circuit is put across the battery's terminals?
That will depend on the internal resistance of the battery. I = E / R Where I is the current, E is the open circuit battery voltage, and R is the internal resistance of the battery.
What is maintained across the terminals of a battery?
Current
How is a series circuit different to a parell circuit?
The difference between a series and parallel circuit is that a series circuit is connected in such a way that the same current intensity flows through the elements while a parallel circuit is connected in such a way that the same potential appears across their terminals.
What is use of terminals in the circuit?
Terminal represents or are ends in a Electrical Circuit that connects components in Circuit to the Power Source. Terminals are either Positive or Negative marked at the ends denoting the acceptible floe of electrons across the Circuit.
Why always voltmeter is connected in parallel with load terminals?
A voltmeter is connected in parallel with load terminals because it is designed to measure the voltage across those terminals without significantly affecting the circuit. When connected in parallel, it can accurately capture the potential difference across the load while maintaining its high internal resistance, which minimizes the current drawn from the circuit. This ensures that the measurement reflects the actual voltage present across the load, allowing for precise voltage readings.
Does voltage flow across a circuit or is it impressed across a circuit?
Voltage is impressed across a circuit. Current flows through a circuit.
Do You measure current across a circuit?
A current flows through, not across, a circuit. And, yes, you can measure it using an ammeter.
What happens in a circuit to voltage when current flows?
A: There is a relationship one needs the other both can coexists but not each alone.
How many terminals does watt meter have?
A wattmeter typically has four terminals: two for the voltage connection (potential terminals) and two for the current connection (current terminals). The voltage terminals are connected across the load to measure the voltage, while the current terminals are connected in series with the load to measure the current. This configuration allows the wattmeter to calculate the power consumed by the load.
