Why voltage measured at terminals of battery to which load is connected is always lower than open circuit voltage?
Real-world batteries do not have zero internal resistance. When one connects a load (resistance) to a battery, current begins to flow and the open-circuit potential is divided between the battery's internal resistance and the resistance of the load. Thus, one will measure a lower voltage at the battery terminals when a load is connected, compared to no-load conditions.
What else can I help you with?
Does miliamperes increase as does battery voltage when put in a series configuration?
The current in a circuit, expressed in milliamperes, is1,000 x (battery or power supply voltage)/(resistance connected between the power supply terminals)If you increase the voltage of the battery or power supply, the current in the circuitincreases proportionally, at least until something in the circuit gets hot, melts, fuses,and opens the circuit.
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 the function of a variable resister in an electrical circuit?
A variable resistor usually has three terminals, one of which is connected to the 'wiper' by which means its resistance is measured. By using all three terminals, we can control the potential difference in a circuit. When used in this way, we call the variable resistor a 'potentiometer'. By using two of the three terminals, one of which must be connected to the variable wiper, we can control the current passing through circuit. When used in this way, we call the variable resistor a 'rheostat'.
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 can be used to produce a continuous flow of charge?
A battery will do this, when connected to a closed circuit (for a while).
When the wires are connected to the terminals of the battery what causes electric currents in the circuit?
The energy stored in the chemicals of the battery
When wires are connected to the terminals of the battery what causes electric current in the circuit?
The voltage (V) between its terminals. ~Gabby
When the wires are connected to the terminals of the battery what causes electric current in a circuit?
The resistance of the load is what causes an electric current to flow in a circuit.
Should you connect both ends of a battery in to a circuit?
The circuit won't do anything until both terminals of the battery are connected to the correct [two different] points in the circuit. As long as either terminal of the battery remains disconnected, the circuit is "OFF".
What happens in a battery's negative terminal when it is not part of a circuit?
When a battery's negative terminal is not connected to a circuit, it accumulates excess electrons, creating a negative charge. This creates a potential difference between the positive and negative terminals, which is the driving force for the flow of electric current when the battery is connected to a circuit.
What is the role of the battery symbol in a circuit diagram?
The battery symbol in a circuit diagram represents a power source that provides electrical energy to the circuit. It shows where the positive and negative terminals of the battery are connected in the circuit, indicating the flow of current from the positive terminal to the negative terminal.
What is the difference between short to Battery and Open Load?
Related to a battery and open load is the battery just sitting there without anything connected. A short is a very low resistance attached to the tow terminals of the battery. For example, a wire connected across the battery terminals would constitute a short.
Should you connect both ends of a battery in a circuit?
Yes, both ends of a battery should be connected in a circuit to create a continuous flow of electric current. When one end of the battery is connected to one terminal of a component and the other end to the other terminal, a closed circuit is formed, allowing electricity to flow and power the device.
When an ammeter is connected in a circuit which terminal of the battery must be connected to the positive terminal of the ammeter?
The positive terminal of the battery would be connected to the positive terminal of the ammeter. The load would then be connected between the two negative terminals, positive side of the load being connected to the negative side of the ammeter.
What is the electric current from a battery?
The electric current from a battery is the flow of charged particles, typically electrons, through a circuit. The current is measured in Amperes (A) and represents the rate at which charged particles move through the circuit. It is essential for powering electronic devices and creating electrical circuits.
What are the two places on a battery to which battery circuit wires can be attached?
Positive and Negative Terminals.
