If you had 12 volts across 2000 ohms, you would get 6 milliamperes, not 70 amperes. Ohm's Law: Voltage = Current times resistance.
This situation is impossible per ohms law: E = I x R In order to push 70A through a 2000 ohm reisistor requires 140,000 Volts! In order to get 70A from a 12V supply a 0.171 ohm (171 milli-ohm) resistor is required.
70A @ 12 V is 840 Watts
70A through 2000 ohms is 9.8 Megawatts!! (P = I^2 x R)</P>
What else can I help you with?
What is the current drawn when you have a single phased load of 200KW is supplied at 500v through an overhead line with a resistance of 0.1ohm per conductor?
If the voltage is 500 volts, and the power is 200 kilo-watts, then the current is 400 amperes. (Watts equals Volts time Amperes)The resistance of the conductor has nothing to do with this calculation, but that fact that the conductors are 0.1 ohms means that the voltage drop across each conductor is 40 volts. (Volts equals Amperes times Ohms) Since there are two conductors, the total voltage drop is 80 volts, and the voltage available to the load will be 420 volts.
What resistance in ohms will allow 20 amperes of current to flow in an appliance if the voltage is 220 volts?
The formula you are looking for is R = E/I
What votage will cause an 8 amp current to flow through a 24 ohm resister?
Ohm's law: Voltage equals current times resistance. 8 amperes times 24 ohms equals 192 volts.
What ohm value or what combenation of resistors are needed to draw 20amps at 120v?
ohms = volts/amperes 6 ohms = 120 volts / 20 amperes
Unit of electric power determined by muliplying volts times amperes?
Power=Volts x Amps Unit for power is watts

What is the current through a wire that has a resistance of 30 ohms if the voltage is 90 volts?
The current through the wire can be calculated using Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R). In this case, the current would be 90 volts divided by 30 ohms, which equals 3 amperes.
What votage will cause an 8 amp current to flow through a 24 ohm resister?
Ohm's law: Voltage equals current times resistance. 8 amperes times 24 ohms equals 192 volts.
What does volt times ampers equal?
Volt times amperes equals watts, which is the unit of electrical power. In this context, volts represent the electrical potential difference, while amperes measure the current flowing through a circuit. The formula is expressed as P (power in watts) = V (voltage in volts) × I (current in amperes). This relationship is fundamental in electrical engineering and helps in calculating the power consumption of devices.
2 volts divided by 100 kOhms equals how many milliamps?
2 volts across 100 kOhms produces 0.02 milliamps (or 20 microamps) of current. Ohm's law: Voltage = Amperes * Ohms, so Amperes = Voltage / Ohms.
What is the power dissipated by a resistor that has 5 amps flowing through it with 120 volts applied?
The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).
How 10kw at 240volts what is amps?
Pwer is volts times amperes. 120 volts times 10 amperes = 1.2 KW
10 ohms plus 9 volts equals how many amps?
Ohm's Law: Voltage = Amperes times Resistance 9 volts = amps * 10 ohms amps = .9
How many volts can you get from 260 watts?
It depends on how many amperes there are. If you have 1 amperes, then you get 260 watts. If you have 260 amperes, then you have 67,600 watts. If you have 0.001 amperes, then you have 0.26 watts. Its just watts = volts times amperes. Of course, the limiting factor is the available power behind the 260 volts, but you did not say anything about that.
How can you convert amperes in to volts?
Amperes does not convert into volts they are two different values. Become familiar with the following formula and look at the relationships between the values. Volts = Amps x Resistance, Amps = Volts / Resistance and Resistance = Volts / Amps.
How many Watts in 200 Volt?
To determine Watts from Volts, you also need to know the current in Amperes (A) using the formula: Watts = Volts x Amperes. Therefore, 200 Volts alone cannot be converted into Watts without knowing the current. For example, if the current is 10 Amperes, then the power would be 200 Volts x 10 Amperes = 2000 Watts.
