Is electricity from chemical action always alternating current?
No, Electricity from Chemical reaction may be DC.e.g Battery
Can you charge a 120 volt DC battery pack with 120 volt ac current?
No! and you might have a nasty fire with sulphuric acid spilling everwhere. A battery pack is always DC and it must always be charged with DC. It must also have a device for limiting the charging current, and good chargers also cut the charging current off when the right voltage is reached.
Why was the capacitor discharging current negative?
When a capacitor is discharging, current is flowing out of the capacitor to other elements in the circuit, similar to a battery. Current flowing out of an element, by convention, is defined as negative current, while current flowing into an element, such as a resistor, is defined as positive current. Thus a discharging capacitor will always have a negative current.
A resistance of 10 ohms is placed across a 9 volt battery what current flows through the battery?
No current flows through the battery. There is a current through the external circuit. I = E/R = 9/10 = 0.9 amperes.
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 type of current will a circuit that involves a battery and electrons traveling in one direction have?
a battery always produces a direct current.the electrons always travel from the negetiove to the positive terminal.But the direction of the current is the opposite that is from the positive to the negetive terminal.
How do you increase current in a battery?
we can increase the current in battery by using current amplifiers or chopper's s the easy way to increase the current in battery........
Is electricity from chemical action always alternating current?
No, Electricity from Chemical reaction may be DC.e.g Battery
Is the direction of current through a battery always from negative to positive on the terminals?
Conventional current flow is from positive to negative. Electron flow is from negative to positive
If you park your car and don't drive will the battery die?
The battery will discharge if left for a long time as some current always drains to Earth. They can normally be recharged.
Can you charge a 120 volt DC battery pack with 120 volt ac current?
No! and you might have a nasty fire with sulphuric acid spilling everwhere. A battery pack is always DC and it must always be charged with DC. It must also have a device for limiting the charging current, and good chargers also cut the charging current off when the right voltage is reached.
Does a battery deliver a direct or alternating current?
A battery delivers a source of direct current.
What is the electric current from a battery?
A direct current is obtained from a connection to a battery.
What is the current in a 1.5V Alkaline battery?
The current depends on what is connected to the battery's terminals. If nothing is connected to it, then there is no current, and the battery lasts quite a while. In general, the current is 1.5/resistance of the external circuit connected to the battery until that number gets too big, and then the voltage of the battery sags, because it can't deliver that much current.
What is current in the battery called?
A battery contains a charge of electrons. When these electrons leave the battery and travel through a circuit that is described as current.
Will a battery provide direct current or alternating currrent?
A battery provides direct current (DC).
Why DC is used in battery's?
dc in battery stands for direct current .ac is alternating current.
