You don't. Othewise your local power company could charge you for 1,000,000 kilowatt hours of electricity used by your 120 volt outlet that doesn't have anything plugged into it.

Michael Faraday did not invent or discover electromagnetism. After Hans Christian Oersted discovered it he simply studied it more.

Its A Candelabra base bulb :-)

However, one can find "medium" sized base bulbs marked "Type B."

It prevents the voltage spike that occurs when the magnetic lines of force cut across the solenoid windings when someone shuts the power off the solenoid. It is called inverse voltage and on a 12 volt coil, when you turn it off, the collapsing magnetic field can generate an inverse voltage of 200 volts or more for a split second. This is why sometimes you can get a "poke" out of a 12 volt system. It is the inverse voltage spike that causes a momentary shock to your fingers or body. (this momentary voltage is not harmful to a human). when a coil has a charge cause by applying DC and suddenly disconnected this charge will manifest as a voltage of opposite polarity across the coil the diode will clamp this charge to .6-.7 v removing reverse breakdown voltage present

yes and no if they are inline 6 cylinder engines they will work all but the power steering bracket and the altenater bracket you will have to switch them one from the other

A magnet rotating inside a coil of wire will induce a current in the wire. Disassemble a bicycle generator and that is what you will find inside, a magnet attached to the input axle surrounded by a coil. The current generated will be alternating current because the magnetic field reverses every 1/2 rotation. Frequency will depend on the speed of the input axle, which is of course dependent on the speed of the bicycle itself.

1. Draw the circuit:

A single voltage source in series with Resistance Rs (source resistance) and Rl (load resistance)

2. Using Ohm's law, you know V / R = I, so:

V / (Rs + 4) = 1.5 and V / (Rs + 9) = .75

Solve for Rs: Rs = 1.0 ohms.

Then solve for V: V = 1.5(Rs) + 6 = 7.5 volts

3. Determine the voltage of each cell (assuming they are equivelant voltages):

7.5/5 = 1.5 volts

lf all resistors are in parallel, yes. If they are in series, not necessarily - this depends on the resistor values (if they are all the same, then yes, if not no).

There was a 440 Volt Rating. Voltage ratings of the past gave way to higher levels to allow larger power dissipation from the same wire size. In home use 110 Volts gave way to 115 Volts and that gave way to the 120 Volts of current use. Higher voltages also increased in turn as 110V associated with 220 and 440 Volts, became 115V associated with 230 and 460 Volts, and today we have 120V associated with 240 and 480 Volts.

a shifting magnetic field exposed to a conductor will cause electric current through the conductor. For this reason, you can get shocked by a power pole by holding a copper rod underneath it parallel to the wires. the energy directly between two wires is enough to burn you, that's why the high voltage ones are higher off the ground and aligned up and down.

The effect of an RL circuit in half wave rectifier is that the voltage output wave forms for current and voltage will be modified .

The easiest way to control any electric current to any device is with the inline use of either a manual or electric reistate.

A: There are photo detector that sense changes in light as movement and there are frequency detectors that sense frequency shift as a person disturb the signal. Both are effective withing a certain range depending on environment and sensitivity. HOW TO TRIP IT IS UP TO YOU.

Voltage and resistance are distinctly different quantities. I can say some voltages have very low resistances (and high currents), such as when you drop a hair dryer into the tub. You're question as it is written does not make sense.

Any gap in a series circuit causes the whole thing to stop working. That is why houses are wired in parallel with each other, and indeed there are many parallel circuits inside each house.

Currently Polaris is the best brand on DC generators. Hitachi and Coleman also make very reliable ones.

A 60Hz synchronous motor spins at synchronous speed - if it's a two pole motor it will spin at exactly 1800 rpms. An asynchronous motor will spin at a speed lower than the power supply frequency - a symilar asynchronous motor may spin at 1700 rpms.
