What is the principle of ballistic galvanometer?
The ballistic galvanometer principle states that when a current-carrying coil is suddenly disconnected from a source, the coil carries on moving because of its momentum. The deflection of the coil is proportional to the charge that passed through the coil while it was connected.
What happen when electric current is passed through water'?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
Why steady deflection comes in ballistic galvanometer?
Steady deflection in a ballistic galvanometer occurs because the coil has momentum when current is flowing through it. As the current is interrupted by a switch, the coil continues to rotate due to its inertia, resulting in a steady deflection. The deflection angle is directly proportional to the total charge that passed through the coil during the pulse of current.
What happens when electric current is pass through a colloidal solution?
When an electric current is passed through a colloidal solution, the colloidal particles may migrate towards the electrodes due to the electrical charge. This process is known as electrophoresis. Additionally, the movement of colloidal particles may cause them to coagulate or form larger aggregates.
What is Ballistic galvanometer Explain its construction?
A ballistic galvanometer is used by electricians to measure an electric current. It is commonly used to test whether or not an electric current is present. A ballistic galvanometer consists of a meter that is attached to two probes, one positively charged and one negatively charged. This keeps the user from being electrocuted when an electric charge is present.
What Things do Conductors Have in Common?
If you are talking about electricity then all conductors have either de-localised electrons in their structure which means when a current is passed through they will move and carry the current with them. Ions can also carry charges but they have to be in solution or in liquid form.
How much electrical current is passed through an ammeter in a time of 6 seconds if the ammeter reads 1.8 amps?
1.8 amps of current passed through. I'm assuming you meant electrical charge however, in which case 1.8 A * 6 s = 10.8 C of charge passed through, where C stands for Coulombs. That is equivalent to roughly 6.74 X 1019 electrons passing through.
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
What is the principle of ballistic galvanometer?
The ballistic galvanometer principle states that when a current-carrying coil is suddenly disconnected from a source, the coil carries on moving because of its momentum. The deflection of the coil is proportional to the charge that passed through the coil while it was connected.
When an electric charge is passed through a gas what is created?
light
Are body fluids good conductors of current?
When a current is passed through the body, the water-containing fluids primarily conduct the electrical current. Water is found both inside the cells, intracellular fluid (ICF) and outside the cells, extracellular fluid (ECF). At low frequency, current passes through the ECF space and does not penetrate the cell membrane. At high frequencies however the current passes through both the ICF and ECF...
What is the difference between a electrical conductor and a electrical nonconductor?
Simply put an conductor is a material that lets free electrons flow through it. When free electrons are flowing that is called current. So an electrical conductor will have current pass through. Non-conductive material will not allow these electrons to flow and no electricity can be passed through. Good conductors have almost no resistance to electron flow.
Does copper get heated when electric current is passed through?
yes it does
Why D.C. current is not passed from our body?
Lightning is a DC current and it will pass through your body with devastating effect. Defibrillators use a DC current to restart/reset your heart if it has stopped or gone into fibrillation. So DC current is passed through your body.
What is Primary Current?
Primary current is a flow to be measured that cannot be safely passed through the measuring device. A current transformer is used to provide a lower level, secondary current that can be passed safely through the measuring device. Primary current is measured as a secondary current, multiplied by the turns ratio in the current transformer.
How is immunoelectrophoresis done?
Immunoelectrophoresis is performed by placing serum on a slide containing a gel designed specifically for the test. An electric current is then passed through the gel, and immunoglobulins, which contain an electric charge, migrate.
Which material produces heat energy when current is passed through them?
Actually, ALL materials do ... at least, all materials that you're ever going to see outside of a laboratory or a stripped down MRI machine. The only exceptions are the so-called "superconductors", which have zero resistance and don't dissipate any electrical energy.
