There is no such thing as an 'induced current'. What is 'induced' is a voltage. The direction of the induced voltage is determined by the direction of the changing current that induces that voltage, because the induced voltage will always act to oppose that change in current. So, if the current is increasing, then the direction of the induced voltage will act to opposethe increase in current. If the current is decreasing, then the direction of the induced voltage will act to sustainthat current.
Current flow direction is not dependent on whether or not it's in a series or parallel circuit. Current directional flow is solely determined by the power source. For businesses and residential power, utilities use various forms of alternating current. For example, the United States utilizes alternating current that changes directional flow 60 times per second. Some parts of Europe use alternating current that changes direction 50 times per second. Many electronic devices use a direct current source in which the current flow is only in one direction, from negative to positive or a converter that changes the alternating current source power to direct current.
The domestic electricity supply is alternating current. Instead of a steady flow of electrons through your appliances, there is a movement in one direction followed by a movement in the opposite direction. For heating and lighting, alternating current has exactly the same effect as a direct current. Devices like transformers will only operate with alternating current. Hertz measures the number of cycles of positive and negative current per second. In the USA, the standard frequency is 60Hz and in Europe it is 50Hz. Now we come to the concepts of voltage and current. To understand the mains voltage, think in terms of electric pressure. The voltage is there whether you have anything plugged in or not. It rises to a maximum value, falls to zero then rises to a negative value and falls to zero again, all depending on the number of Hertz or cycles per second. For current, think in terms of the amount of electricity passing through the circuit per second. The amount of current that will flow depends on what you plug in. A lamp will draw a lot less current than a heater. Hertz doesn't have a direct relationship to the amount of current. It is a measure of how frequently the current changes.
An amp meter connected in series with the load will show whether or not a current is flowing in a circuit.
Usually a voltmeter is connected across the load whether or not it is AC (Alternating current) or DC (Direct Current). A voltmeter is never connected in series with the load as this may cause serious injury or damage. The meter will absorb the full potential .
The electrode. In some cases thin materials weld better with DCEN.
Depends whether Direct Current or Alternating Current. Only Alternating Current produces magnetic field.
A megohm is a unit of resistance to the flow of electricity. The requirements of motors are given in terms of voltage, current, whether they are direct or alternating current and, if alternating current, the number of phases.
No, This will act in reverse.Note: This will act only for alternating current and there will be no effect on direct current.
The ratio of the primary winding turns to the secondary winding turns. This governs voltage which is directly related to the current and load.AnswerA transformer increases or decreases voltage, notcurrent. The secondary current is determined by the load, and the secondary current determines the primary current. If there is no load, then there is no secondary current, and the primary current is mainly made up of the magnetising current.
compressing a coil in a magnetic field means that there is a relative movement of the the said coil existing in a magnetic field, hence current will be induced. induction law.Another Answer'Current' is not induced into a coil. It's voltagethat's induced; if the coil forms a closed loop, then current will flow; if there is no closed loop, then no current will flow.The induced voltage results from either a change in current through the coil, or from the relative movement between the coil and an external magnetic field.
Well, voltage and current levels being identical, alternating current would be safer. It does not spend 100 percent of its time at peak voltage, therefore the average power in case of an electric shock is lower than that of direct current, which is 100 percent. This lesser average may allow some time to detach from the circuit and may not cause such catastrophe to the body.
An evaluation to determine whether the system is operationally acceptable. it also determines how the proposed system will fit with current operational system.
Whether your foot is on it or not.

When the current in a conductor reverses direction periodically, that type of currentis categorized as "Alternating Current" (AC).Whether the reversals occur several times per second or once a month is irrelevant.
The magnetic lines of force surrounding the bar magnet, cut through the coils of wire, causing electrons to move. This induces an electric current. It is the movement that is important, whether moving into, or out of, the coil.
The moon determines if there will be high or low tides.
