Depends on the load, and on how the cells are hooked up, series or parallell.
The amperage drawn from batteries is governed by the connected load. The voltage of the batteries can be one of two voltages. in parallel the 8 batteries will give you a voltage of 6 volts. In series the 8 batteries will give you a voltage of 48 volts. The amp/hour capacity of the batteries will give you the amount of current the device can draw over a specific length of time. Equation to fine amperage is I = W/E, Amps = Watts/Volts. Watts = Amps x Volts.
60 amps
Generally 40 amps continuous or 50 amps surge is safe.
It is drawing .06 amps.
8
The short answer is yes 1. make sure you are getting enough amps for the application. A V-8 diesel which may times has two batteries needs somewhere near 1000 cold crank amps total 2. if the vehicle did not have two batteries from the factory but you wish to add a second battery please see a qualified technition before doing this. You may have another issue that is easily repaired.
at least 6 or 8 and the type of batteries are aa bateries sometimes D batteriess
To calculate watts, you need to multiply the voltage (in volts) by the current (in amps). For the 208 volts, 8 amps heating element: Watts = 208 volts * 8 amps = 1664 watts For the 110 volts, 8 amps heating element: Watts = 110 volts * 8 amps = 880 watts
Depends on power factor, but it should be about 8 Amps.
A typical car stereo contains 4 amps. It is rare to find a car stereo without amps. Cars usually can contain up 8 amps, but you could always add more.
80% of the rated circuit. 10 amp circuit is 8 amps, 20 amp circuit is 16 amps, etc.
It depends on the voltage and whether the lamps are actually 40 watts or 40 watt equivalent. Watts / volts = amps
