How long does current flow in one direction when 60hertz(60cycle)current is used?
In a 60Hz AC current, the current flows in one direction for half of the cycle (1/120th of a second) and then reverses direction for the other half of the cycle. This continuous reversal of direction is what allows electric devices to function properly.
What is the relation of Figure of merit with current sensitivity?
The figure of merit is used to evaluate the performance of a sensor by considering factors like sensitivity, resolution, and noise. Current sensitivity specifically refers to the ability of a sensor to respond to changes in current. A higher figure of merit indicates better overall sensor performance, which can be influenced by the current sensitivity of the sensor.
What will induce an electric current in a wire?
There are two ways of doing this; 1) moving a magnet perpendicular(at right angles) to a coil of wire 2) placing a coil of wire in close proximity to another coil carrying an AC current.
Why and when does a current carrying conductor kept in a magnetic field experiences a force list factor on which the direction of this force depend State the rule which may be used to determine the di?
Current carrying conductor will have magnetic lines around it. So when it is kept perpendicular to the magnetic field then the force would be maximum. The force depends on 1. magnitude of current 2. Magnetic field induction 3. Angle between the direction of current and magnetic field. Fleming's Left hand rule is used to find the direction of force acting on the rod
What the two main type of wave?
transverse and longitudinal Well, it depends on what your teacher explained. However earthquakes can be: 1) tectonic, 2) volcanic or can be 1) natural, 2) induced (that is induced by human activity, such as mines and reservoirs). Any scientific site like that of the USGS could be a useful source of information.

What are the different ways to induce current in a coil?
Different ways to induce current in a coil are as given below:(1) If a magnetic field is changed round a coil then an induced current is set up in the coil. It can be done by taking a bar magnet and bringing it closer to the coil or taking it away from the coil.(2) If a coil is moved in a magnetic field, then again an induced current is set up in the coil.(3) If a coil is rotated in a uniform magnetic field, it may also cause an induced current in the coil.(4) If we take two coils and insert them over a non conducting cylindrical roll then on changing current flowing in one coil, an induced current is obtained in the other coil.CommentYou don't induce a 'current' into a coil; you induce a voltage. If that coil is open circuited, then no current will flow. If, on the other hand, the coil is connected to a load, or its opposite ends short-circuited, then the induced voltage will cause a current to flow. Remember, current will only flow if there is a load, or short circuit, and the value of the current will depend upon the value of the induced voltage and the resistance of the load or short circuit.

What changes the flow of electrons in an alternating current?
first of all the voltage doesn't change what changes is the current direction the way they do it is by using magnet . electrons tend to escape from the magnetic field . you can find on you tube how a motor works for better idea.

How the superposition theorem is used to find the currents in a circuit supply by more than one voltage source?
1.Put a short circuit instead of voltage source 1 and find what you want with taking direction of current in that element(ris.ind.cap.) 2.puta short circuit instead of voltage source 2 and find what you want with taking direction of current in that element(ris.ind.cap.) 3.add current 1 and 2 for any element.
Magnetism can sometimes be induced in an iron object by?
1.Stroking it with a magnet 2. Applying a current to a coil of wire wrapped around the iron
What is the net resistance of the circuit connected to the battery in Figure 1?
The net resistance of the circuit connected to the battery in Figure 1 is the total resistance that the current encounters when flowing through the circuit. It is calculated by adding up the individual resistances of all the components in the circuit.
How many American children have autism?
The current figure for Autism diagnosis is 1 in 55 children. Obviously this figure could be incorrect due to a number of factors, including under-diagnosis in minority groups and girls.
