How many amps will you get on a 9 volt battery with a 100 ohm resistor and a 100 ohm resistor and a 470 ohm resistor?
You need to calculate the equivalent resistance. For instance, if the three resistors are connected in series, simply add all the resistance values up. Then, you calculate the current (in amperes) using Ohm's Law (V=IR); that is, you need to divide the voltage by the resistance.

How many amps will a 260 ohms resistor on a 120 volt circuit use?
Just use Ohm's Law Voltage = Current x Resistance Amps = Voltage Divided By Resistance Amps = 120 / 260
In order for a 30 volt 90 watt lamp to work properly in a 120 volt supply the required series resister in ohm is?
A 30 volt 90 watt lamp has 3 amps going through it. The series resistor also has 3 amps going through it, by Kirchoff's current law. The voltage across the resistor is 90 volts. With 3 amps, that is 30 ohms. (By the way... The resistor must be rated to carry 270 watts. That is a lot of power for a resistor.)
What is the resistor of 18 ohms when connected to a 9v battery?
Even though it is connected to a 9 volt source, it is still a resistor.
If two bulbs in a series are connect to a battery and the current in the first bulb is found to be 1 ampere then what is the current through the battery?
A circuit with a 2 ohm resistor and a 4 ohm resistor in series with a 12 volt battery will have 2 amps flowing through each resistor. The current is the same in each resistor because they are in series, and a series circuit has constant current throughout.
What charger do you need for a 24 volt battery?
The formula you are looking for is I = W/E. Amps = Watts/Volts. 300/24 = 12.5 amps. A good charger with an output of 15 amps will do the job nicely. The time that it will take to charge the battery will depend on the amp/hrs of the connected battery and the state of discharge that the battery is in when charging starts.
How many volt amps in 12 volt battery?
Depends on the battery. It is listed on the battery as Cold Cranking Amps (CCA).
What is the amps In a simple electric circuit with a 12 volt supply and a 24 ohm resistor?
0.5 amps
How many amps and volts in a car battery?
modern cars use a 12 volt battery. Amps depends on the battery. Common sizes range from 500-800 cold cranking amps.
How many amps are in a 6 volt battery?
The number of amps in a 6-volt battery depends on its capacity and design, typically measured in amp-hours (Ah). For instance, a 6-volt battery rated at 10 Ah can theoretically provide 10 amps for one hour. However, the actual current (amps) drawn from the battery varies based on the connected load or device. Therefore, without specific details about the battery's capacity and the load, it's impossible to determine a fixed number of amps.
Two resistors are connected in series to a 9 volt battery. The larger resistor provides twice as many ohms resistance as the smaller one. The current through the circuit is 3 amps. What is the resista?

How many amps are in 40 volt amps?
Multiply the vots by the amps to find the volt-amps. Or divide the volt-amps by the voltage to find the amps.

How long to charge a 12 volt battery at 2 amps?
It takes between 8 and 12 hours to charge a 12 volt battery at 2 amps. The actual time will depending on how much charge is in the battery initially.
How many watts does my 12 volt 2 amp battery charger draw?
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
A 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor What is the current in the circuit?
If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in series, the current in the circuit is 1.0 amperes. If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in parallel, the current in the circuit is 0.5 amperes.
