How do you switch the voltage requirement for a cooktop from 208 volts to 110volts?

You don't. The cook top was designed to operate on 208 volts. This is the voltage needed to get the elements up to their rated wattage to do the cooking. Higher wattage appliances do not operate on the lower voltage because of the size of the wire that is needed to feed the appliance.

Measure the voltage across a voltmeter and a switch?
If the switch is closed (connected) the voltage across it will read 0V. If the switch is open (disconnected) the voltage across it could be anything, it just depends on what the voltage between the wires going into the switch is.
When measuring voltage drop across a switch what is the maximum allowable voltage drop?
The voltage drop should be as close to zero as would be readable by a typical volt meter. If it is measurable you likely have a problem with corrosion or oxidation in switch that is increasing resistance. If you can measure a voltage drop across a closed switch contact, replace the switch. Or the switch is open, try flipping the switch!
In a circuit if the switch is closed how many volts go across the switch?
For an ideal switch, there will be no voltage drop across it. In reality, there will be a very small voltage drop, and this will be dependent on how well made the switch is, and what it is made out of.
How do i switch a 3 phase motor from low to high voltage?
You can't. You must supply the motor with it's required voltage. If it's a dual voltage motor, follow the wiring schematic on the motor nameplate to switch from low to high voltage.
The voltage measured directly across an open switch in a circuit will be?
The voltage measured across an open in a series circuit is the equivalent of the sourse voltage.
What is the Location of medium voltage switch gear?
A medium voltage switch gear is on the low voltage side of the transformer. This medium voltage switch is very cost efficient as well.

What is the definition of a dimmer switch?
A switch that regulates voltage to something.

What voltage is measured across an open fuse or switch?
The full circuit voltage
Feed drops to zero volts when light switch is turned on back to 120 volts when turned off feeds fluorescent lights?
voltage is measured by voltagd drops. When a switch is open/ off there is a voltage difference between one side to the other. when the switch is on there is no drop from one side of the switch to the other. That is normal operation. If switch is on, and you get a voltage reading across the switch, the switch is bad.
How do you determine if the light switch has power?
You will need a voltage tester to determine this. Put the tester across the top screw on the switch to the ground wire in the switch junction box. If there is an indication of voltage you can assume that the problem is further down the circuit. If there is no indication of voltage on the top screw then test between the bottom screw on the switch to the ground wire. Sometimes the "hot" is on the bottom screw. If there is no voltage present at the switch you have to work your way upstream towards the distribution panel to see what is interrupting the voltage.

When a solenoid switch goes is it ok to charge a battery?
yes, it's OK to charge the battery. A switch like this is controlled by voltage so low voltage could make the switch not work.
How can you determine if their is power at a light switch?
Use a volt meter to measure the voltage to neutral on each side of the switch. By turning the switch on and off and monitoring the voltage on one side and then the other, you can determine the supply and load side of the switch.
Is a resistor and a relay the same thing?
No, they are not the same. A resistor is a current reducer and a relay is essentially a switch (using low voltage to switch high voltage on/off)
