Yes, when using a step down transformer the amperage is affected.

Do not hold the thermometer by the bulb while reading it.

no

An ammeter measures amperage not voltage.

Multiply (1,000) x (Voltage) x (Amperage) and you have KW. Multiply that by the number of hours you use it, and you have KWh.

they would get soil reading from the short one, obviously, and body readings from the long one.

Wire size is based on the amperage drawn. To find the amperage, the voltage must be stated. Use this formula to find the amperage. I = W/E. Amps = Watts/ Volts. Once you have the amperage, restate your question using the new found amperage or state the voltage that supplies the lights.

Larger wires will not reduce the amperage draw of a device. Limiting amperage draw is accomplished by fuses wich blow when the amperage drawn across them exceeds their specifications.

Look on the appliance's nameplate. All appliances have one. There it will tell you what the amperage is. If not the amperage then it will tell you the watts the appliance uses. Use the following equation to find the amperage if the nameplate only states the watts. Amps = Watts/Volts. This will tell you what the amperage of the appliance is.

The formula for amperage is:I = V / RI = amperage, V = voltage, and R = resistance.Also amperage can be found by using the following formulas.I = P / V, Amps = Watts/VoltsI = sq root P/R, Amps = the square root of (power divided by resistance) watts/ohms.

This depends on the amperage of the battery. Wattage (400) = Voltage (24) x Amperage (???). Once you can determine the amperage per hour you can determine how long the battery will last.

The easiest method today is by using a clamp meter. It "clamps" around a single conductor and measures the magnetic field (you can't get a reading by clamping around a regular appliance cord, as both conductors will cancel each other out).
