That's Ohm's law. Volts = Current (or Amps) * Resistance.

What is the relationship between ohms resistance and amps for current?
The relationship is expressed by Ohm's Law: V=IR (voltage = current times resistance).
How can you solve for resistance when given power?
Depends on the voltage. R equals V2/P . Or the current: R equals P/I2 .
Does ohms law state that current equals flow of electrons through a conductor?
No. Ohm's law relates voltage, current and resistance: V=IR. ("I" is the symbol for current.)
If current in an electric stove is doubled how will the thermal energy produced per unit time change?
P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.
If the voltage is 12 volts and the resistance is 3 ohms what are the amps in this circuit?
Using Ohm's law, we can find the current (I) in a circuit where 3 ohms is the resistance (R) and 12 volts is the appllied voltage (V). [(E) means energy]I = V / R = 12 / 3 = 4 amps.Visit this link http://www.csgnetwork.com/ohmslaw2.html for making Ohm's Law calculations.
If voltage equals resistance x current then?
Ohm's Law: Voltage equals Resistance times Current Given any two, you can figure out the other using simple algebra.
How do you calculate power loss from a resistor?
The power dissipated across a resistor, or any device for that matter, is watts, or voltage times current. If you don't know one of voltage or current, you can calculate it from Ohm's law: voltage equals resistance times current. So; if you know voltage and current, power is voltage times current; if you know voltage and resistance, watts is voltage squared divided by resistance; and if you know current and resistance, watts is current squared times resistance.
How is current related to resistance in a circuit?
Ohm's law: voltage is current times resistance. Restating this; current is voltage divided by resistance, so increasing resistance would decrease current.
An electric heating element has a resistance of 16ohm and is connected to a voltage of 120v How much current will flow in the circuit?
Ohms law states that E=I * R, or voltage equals current times resistance. Therefore current equals voltage divided by resistance. 120v divided by 16 ohms equals 7.5 amps.
What does l represent in electrical?
It usually represents current in amps as in the equation V=IR (volts equals current times resistance)
What is the voltage across a load given that the current though it equals 30mA and resistance of the load is 1000 ohms?
Ohm's law: voltage is current times resistance 0.03 amperes times 1000 ohms = 30 volts.
What happens to the current in a circuit if the resistance is increase?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
What happens to the current in the circuit if the resistance is increased?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
What happen to the current in a circuit if the resistance is increased?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
Does voltage divided by watts equal the current?
Electric power is not defined as current divided by voltage. Electric power (Watts) is equal to amps times voltage
What is the voltage drop of a 1k ohm resistor?
It depends on the current going through it. Ohm's law: Voltage equals current times resistance.
What will be the load voltage if load resistance is 10 k ohm and load current is 2 ma?
Ohm's Law: Voltage is equal to current times resistance 0.002 amperes times 10,000 ohms equals 20 volts.
