Unless otherwise specified, all a.c. voltages and currents are expressed in root-mean-square (rms) values. An rms value is exactly equivalent to a corresponding d.c. value. So, 230 V a.c. is exactly equivalent to 230 V d.c., and 10 A a.c. is exactly equivalent to 10 A d.c.
Incidentally, the symbol for volt is 'V' (not 'v') and the symbol for ampere is 'A' (not 'a').
If you are talking about a 6 volt coil, yes, so long as the contacts are rated for the 230 volt circuit. If you are talking about 6 volt contacts, no, absolutely not.
Yes. Power in both cases is 1.035 KW. Your meter shouldn't know the difference.
Yes you can .connect the 230 volt capacitor series with the relay coil.AnswerIf you are referring to the operating coil, then the answer is of course not, as you will be subjecting the coil to nearly 20 times its rated voltage! If you are referring to the contacts, then you need to check the nameplate data for the relay to find out what voltage the contacts are designed to operate at.
a 3 phase 415 volts 50 HZ 15 HP motor draws: 1. On no load 3.6 amp after a starting kick of around 18AMP 2. On a full load : a starting kick of 108 amp for few seconds and then18.3 amp. 3. On rated load(this means the motor is selected such that the load is 80% of the motor capacity) 14.64 amp with a starting kick of 88Amp.
Since this is basically a pure resistance load, the DC formula for power will be awfully darn close. That formula says that current times voltage equals watts. Therefore 230 V times unknown amps equals 8000 watts. Or, 8000 divided by 230 equals amps. 8000/230= 34.78 amps, or 35 Amps. This formula doesn't work if there is a reactive load ( a load that involves either coils or capacitors). A heating element involves neither, it is pure resistance.
If you are talking about a 6 volt coil, yes, so long as the contacts are rated for the 230 volt circuit. If you are talking about 6 volt contacts, no, absolutely not.
That is called an inverter.
Watts = Amps X Volts Grab your calculator!
If a precision voltage is needed from 200 to 230 an auto transformer could be used. If the load is a 230 volt motor to be operated on 200 then add 15% to the nameplate full load amperage for the calculation for overload protection.
Yes, you can use a 230 volt device on a 240 volt supply.
The only way to do that is with a transformer. They make inline transformers that convert 230 to 115 and they simply plug in inline.
Yes. Power in both cases is 1.035 KW. Your meter shouldn't know the difference.
No, they do not draw the same current. The current drawn by an electrical device is determined by the power (Watts) and voltage (Volts) using the formula: Current (amps) = Power (Watts) / Voltage (Volts). So, the 12 volt 50 watt bulb will draw higher current compared to the 230 volt 50 watt bulb.
no
Converting 9 volts to 230 volts would require a pretty hardcore step up transformer (Expensive) and you probably wouldn't have enough current to sustain the load.See discussion page for more information.
No.
Yes, we have a 230-volt plug adapter available for purchase.
